It's June and the "Beta Test Agreement" requires me to destroy all copies of the Betas after "May 31, 2013":
2. License. Company grants to Participant a non-exclusive, non-transferable license to use the Software on a single computer solely to internally Beta Test the Software until May 31, 2013 (unless terminated earlier as provided herein) at which time the Software and all copies shall be returned to Company, or destroyed and verified by Participant as having been destroyed.
I've done this, but in case there there will be a Beta7, I thought I'd offer this reminder that you'll need to update the agreement.
Thanks for the beta testing offer,
-Pete
