People who know more about #oss#license then I do:
I think it really shouldn't be a issue to relicense code from the PHP 3.0 to the PHP 3.1 license, but would it also be possible to relicense it to MIT without contacting each author?
BTW, I recently had a trip down #memoryLane and realized that I might technically count as a #publishedAuthor. The story goes like this: a long long time ago in an Internet far far away, there was a social network that started in the best way: as a #POSSE aggregator. The name of the network was #FriendFeed, and apparently it reached its highest reach among users in Italy and Turkey.
(Why? No idea.)
