Ah ok.
Well, never mind not exact strictly following the SVN convention then
If you really want I can move it around like:
site/trunk -> site/branches/tim
site/branches/Site2 -> site/trunk
Which, I guess, makes a little bit more sense if you are the one actively developing.
OTOH it's just a filename in this case (no issue with being forced to check out a site / spring code you don't need) so I don't think it matters much.
(I don't like making e.g. site/AF/{trunk,branches,tags} and site/tim/{trunk,branches,tags} because that would almost imply anyone with a Spring related website could get access to put it in Spring SVN, which goes a bit too far IMO.)
