Trac seems to be having some performance issues (I can't login either). Everyones currently on holiday who could fix the problem but will pass it on and hopefully it is fixed asap.
We're very sorry, Pike! As Will said, we're out-of-office - back tomorrow.
I've fixed the immediate login problem, although we've got some work ahead of us on that front (both on server maintenance, and finally upgrading trac to avoid the omnipresent MySQL timeouts).
