Happily, it looks like my mention of "no Maliszewski at OSRCon" in a post of five days ago was erroneous. My apologies for the misinformation; it turns out that James Maliszewski will be at OSRCon after all. Huzzah!
As far as my own preparations go, I have almost finished stocking my OSRCon Labyrinth Lord adventure, The Tower of Death, and am planning to run a secret playtest of the module with some friends from my own gaming group in July sometime, to make ready for the August con sessions.
Come join the fun! OSRCon registration is only is $20 CDN until July 1, 2011.
I will be running Labyrinth Lord games during sessions one and three of the con. My GM code on the linked schedule is #6421; I'm at Table 5 both sessions.
