There is an announcement in the SL Blog telling us the Lindens are going to set the SL Forum to read only. Why? To upgrade the forum, blog, and everything… as best I can tell.
See: A Fresh New Community Look is Just Around the Corner!
Starting February 21, Tuesday, the forum will lock. They expect to have the upgrade done by 2/27 or sooner.
Yet another forum? 🙂
No… same one, new software.
