What is it you are trying to do? For the SVN, you can already download it
you just can't commit anything, so you can use the issue tracker to post
your code and one of the developers can review and commit it. I would
presume that if you did enough coding you would eventually be given more
privileges, but that isn't my area or call. :) As for the sign in for the
KA forge, I would guess signing in is for people with edit rights to the
content, so again, you would need to request it to the powers that be. If
that is what you mean, then hopefully someone else from the list will be
able to help you more than me.
