Curiously, GC customer service just told me they do at least one daily push of approved content into the searchable system. They heavily implied if something was in queue last week but hasn't hit yet, then they're awaiting some input from the event owners. So, either something hasn't been communicated back to the BGM team, or the BMG events are being knocked way down (or even out of) the GC web dev's update queue.
This is a major bummer, as registering for these AWESOME sessions is pretty much Top 5 in my overall life priorities right now. I'm sure Baldman et al. are crazy swamped getting ready for D&D Live this weekend, so if the BMG fanbase can help out in any way, just point us toward the objective, yeah? We crave that fresh, delicious content. We hunger. And we are legion.
