Either I lost an email somewhere or Valve is acting earlier than Phoronix said they would.
I was able to log into the Steam Linux Beta without needing to be invited formally by Valve. Again, I’m not sure if I misplaced an email or if its due to custom code (which shouldn’t be the case). So, if you are running Ubuntu and haven’t been invited, please let me know. If you are running Fedora 17 or later (I’m running F17), I’ll see if I can get the repositories posted so you can get in on the action as well…
