Hey - just a little thing that I seem to have resolved myself: I wasn't able to log in after creating a group with a comma in the name... the login error was:

Error parsing https://fold.it/portal/comm/my_group_csv:
Line has too many values.

No problem after I edited the comma out the group name. Not really a bug, but you might want to indicate on the group creation page that there are illegal characters.

Stellar work, all. Love the project.
