Well, from just skimming through it (will give it a good look over later), it seems you have put in a lot of effort.
The only things I have picked up from my quick scan are:
You really need to fix the spelling errors. A post on the forum is one thing, but this is something which people need to read. Poor spelling makes it difficult to read/understand (ie: misspelling LRPC, geothermal, porcing (porching... lol... [sorry, irc in-joke]) and general poor sentence structure) which can make it difficult for new users to get through, and can also lead them astray. Run it through Microsoft Word if you have too.
Secondly, I think you need to reduce the "chatty" tone of the whole thing. It reads as if it were written by an excited 14 year old (no offense intended), and so it doesn't really give the impression of someone who knows what they are talking about. For example, using "internet speak", or throwing in little comments (which on their own aren't bad, if you're saying something humorous, not "every unit explodes├óÔé¼┬ª YAY" [actual quote]), intentionally mispronouncing things like "phew" instead of "few", etc. It just makes the whole guide less respectible, which doesn't match the level of effort you've put in.
Thirdly, you seem to have written much of this off the top of your head (not in itself bad), rather than going out and researching what many people have to offer in terms of strategy as well. Eg:
LRCP The big bertha, yea. Not the ultimate, but several times cheaper and more accurate then a buzzsaw/Vulcan. No good at defending, since their slow targeting makes it impossible to hit moving targets. Try to build one on small maps, or just build one close to the enemy. In fact, build several, whit a lot of AA around em (and ground, if that├óÔé¼Ôäós possible. A LRPC expansion is very useful and can sometimes mean a win for the one hit them.
While you show an understanding of the importance of an LRPC, you don't really explain their essential purpose in the game as a stalemate busting unit. Also, because of their enormous range, such weapons are base busters in medium maps as well. You don't mention the amount of energy it costs to run such a thing, which is essential knowledge tactically. A bit of research would have told you that the Arm Big Bertha is shorter ranged, but significantly more accurate than the Core Intimidator. Further research would have provided the knowledge that placing a metal storage infront of your LRPC acts as a "shield" which can protect that unit from attacks, while still allowing it to fire over (this may not work as well in spring because of the friendly fire issues, but I'm sure nerfing the storage once you build it would provide a nice non-friendly wall).
"The obvious way to kill LRPC is to use planes, since they are fast to enter and kill it all."
I think it is best to leave this to the player to work out. Planes are not always the best way to kill LRPC's. Often the best way to stunt an LRPC is not to hit the thing itself, but to hit its power supply.
[this isn't the only issue, just an example I took at random]
Finally, you tend to approach the way you explain things somewhat haphazardly. You mention expansion and raiding, for example, but you don't mention it in the overall context of the most important part of TA and TASpring, which I will summarise:
Because resources are technically unlimited, the real gauge of resources isn't how much you have but how much you have incoming.
This means that such a game is not a defensive game, but an offensive one. Expansion is they fundamental of TA. The more metal you have incoming, the more plants you can afford to run. The more plants you can afford to run, the more units you can throw at your enemy. Obviously stopping your enemy from expanding is just as important as your own expansion.
Just looking over it while I read your posts, there seem to be a couple of innacuracies, but hopefully people will fix them up.
(I don't like the "PAPER-ROCK-SCISSOR" section - something like that will get a new player killed. It is fairly obvious that AA is meant to kill aircraft, but beyond that counters are never that simple)
And just to cap off, I don't think you should tell people to leave your sections alone. The whole point of a wiki is that it constantly evolves and changes, so that the mistakes you made (and there are a few) are fixed up and added too. I don't even think adding your name is common practice with a wiki.
Also, this was all meant as constructive criticism. It is clear that you have put a lot of effort in, and I'm sure that it will help many people. It is definitely not complete, however, and has some things that need to be fixed up.
Good work.
