First I tried to create an account on the website. I kept getting that my CAPTCHA was invalid, even though Google seemed to think I was fine. Finally, I found this thread that suggested creating the account with BOINC manager. OK, that worked.
Now, I need to set up the TeAm. I go to do that, and it says:
Unable to handle request
You must complete a task to create a team
It looks like the dev fixed account and team creation. I was intending to just test it and (probably) get the error again, but it actually created the team. Let me know when you're ready to have the TAC account take ownership.
