Hey folks, Apparently some of you have attempted to use the ipad app to access these forums and run into a "Please contact your forum administrator to activate ProBoards." message.
Don't fear! AstroPhD is on there!
I've stolen the following advice from the support forum:
Press the "Forums" tab at the bottom of the screen when you load the app, then press the + button in the top right of the screen. Enter the first part of the URL to the forum and continue on (so simply enter astrophd rather than http://astrophd.proboards.com).
