The 2.29 version of GEM has been released with some interesting "features", some of which look more useful than others. From a user point of view, one of the potentially interesting features is the removal of the "throttle" that made GEM so slow to update. You might recall this was added when Blizzard suddenly changed guild and private channels (which is what we use for GEM) to have a limit on how many messages could be sent to the channel over a certain period of time, which caused GEM to start losing information. If this is no longer necessary, GEM updates on the channel should be much faster. This is certainly my hope!
