Jeff Atwood (guy who made StackOverflow/StackExchange) and his team released his new forum software, Discourse, today.

Since you're doing the whole rebuilding Enworld thing right now, might be something worth taking a look at. StackExchange was very well built, had high performance, and its design was excellent for its target market of Q&A sites.
If Atwood has done the same thing with forum software that he did for Q&A sites, this might be another option rather than rebuilding Enworld up from scratch.
(Or it might be terrible, I haven't actually tried it. But StackExchange has built up enough credit with me that I thought I'd make sure you guys heard about this.)
