Apologies folks! Yes, much of the time the slowdown is my fault. I do all my updating of my PbP games at work, in addition to prepping my weekly D&D game that I DM. And when work speeds up, my D&D time focus tends to go to the weekly live game (creating encounters and such).
I'll try and be a bit more dilligent about keeping up the pace, and quite possibly rejiggering the module a bit. This particular one has quite a number of combat encounters in a row, but in PbP that slows things wayyyyyy down. I think I need to find a better split between combat encounters and roleplaying scenes.
And Insight, if you're reading this... I'll keep Gloomblade around in the background, so if at any point you find a free moment occasionally and want to drop back in to post, please feel free. Especially when we reach parts out of combat and its mainly roleplay posts. Take over Gloomblade whenenver you'd like.
