SL16B is coming up, the deadline for exhibitor applications is May 15th.
I just, just found out myself -it seems like LL is taking back the event? The announcements and all are back on the Linden blogs, and the previous slbcommunity blog is out of date. Anyways, that's neither here nor there.
What's more important is -what is the theme? This year the theme is the 1950's ...which will prove a challenge, but far from an insurmountable one.
