Well, I've joined the team and installed the SETI client and it's happily churning away BUT I get the following message when I click the Join link:
Web Page Missing
The page you selected isn't on our server, or currently unavailable due to hardware/software maintenance.
If this is a broken link, please report it to us via the bug report form on our help page - make sure you categorize your report as a "Website or CGI Problem."
If you ended up here while trying to access personal/team stats, or read the newsletters, or submit a bug report form, then CGIs have been turned off. You needn't bother to send us e-mail, as we are quite aware of the problem. Sorry for the inconvenience - we turn CGIs off occasionally when working on the user/science databases.
I will try again tommorow. Thank you all for the assistance and the warm wishes of welcome!
