Apparently my login for Uservoice is only half correct, because it doesn't throw an error but sends me to your site still logged out. I'm very annoyed with the whole thing so I can't even vote on your projects. Have fun with uservoice.
Uservoice is just very finicky about my passwords and such. I logged in with Gmail afterward and that worked, then I tried to link it to my account using a l/p that I know is good, and so it apparently accepted it and forwarded me to problems.startupweekend.com where it suggested I log in. I had a lot of fun doing that dance, and hope to never do it again.
