Runequest 6 by Design Mechanism and Guide to Glorantha by a kickstarter campaign have woken up quite a bit of activity for Glorantha.
RQ6 is excellent ruleset for the game masters and the most fun edition of RQ so far. It has two excellent scenario books already out – Book of Quests and Monster Island both of which can be set on any universe. Monster Island especially is a magnificent tome for the GMs.
RQ6 is still missing the Glorantha parts that are coming in Adventures in Glorantha later. For those that can’t wait there are at least two fan efforts to bide you thru
I found also the following quick reference tables created by Gloranphile very useful.
There is active Glorantha community page at Google+ with lots of old timers but many new faces as well.
