Sorry for the delay on these, we ran into some drawn out host issues.
Few major bugs should be fixed now:
* Signups should now work (haven't tested so if you have an invite test and let me know in the bug forum)
* Non-SSL tracker should be working now
* Emails should be going out now (few quirks but I'm working on those)
I'm still doing some behind-the-scenes restructuring so there could be downtime again at some point.
