Any recommendations for where to find a good PbP site, but one that caters to the Mentzer boxed sets?
rpgloop.net
rpol.net
myth-weavers.net
thetangledweb.net
Those are few good places to look for pbp game, although not specific to ODD. Spam those sites and maybe you'll find some people to form a game with!
You could have a great ODnD PbP game on this site.
