Last night I had this dream... in which I visited the forum here only to find that Aaron Hall had unexpectedly passed away! 8-O But apparently before he died he willed the existing source code to SE5 to the community, and Tesco and David Gervais were starting to head up an effort to build SE5 on their own!
I'm not a lawyer, but if my understanding is correct, let this be a reminder to everyone to will their intellectual property to SOMEONE, ANYONE, so that it isn't lost in the morass of copyrighted IP which no one actually owns! 8-O
