I run and manage a large D&D games-by-message board site at woldiangames.com. We nearly always have at least one opening since we currently run 14 ongoing games. Once started, none of our games have ever folded. Some have been going for 10 years. Check us out and join us if you're looking for a friendly online gaming community.
I've played and DMed DnD since 1980. My local group has been consistent since 1985 as has our campaign world that we all work on. We took it online in 1997. I'm a teacher by trade. Our online games post daily M-F. My local game meets Friday evenings.
