Yeah, the forum has gotten too fast-paced and big to really keep character-per-player-based forum RPs viable here. It's not just the GM needing charisma and updating that's the issue with them - this is an issue with Z-machine style RPs as well, and several of those have also died due to lack of content or interest - it's that content generation for multiple-writer RPs needs more coordination between different people and background planning, which means that new posts are slower. And since this generally isn't enough to keep things on the front page here, it's pretty difficult to make that work as it stands.
And frankly, that's fine. The activity and speedy/spammy RPs that are here are nice, and things are going well anyway - Rumia's has a nice niche as it is, and I don't think that needs to be messed with.
But if people are worried about making slower forum RPs like that seem unwelcome, a compromise would be to encourage threads for organizing those here, while facilitating/endorsing/outsourcing a slower location for the RPs themselves elsewhere. What little active stuff there is for WuftD has been largely moved to Nemo ma's forum, as Gap had actually been considering since a few months back: Helping get initial organizational threads ready here and providing links to resources to set up a similar small, free forum for the RP itself elsewhere might be a good way to support it without having to mess with what we have going now. Endorsing them by keeping the original planning thread around and including summaries/links to the external board RP in the game archive would let the presence stay, if only in a small way.
Of course, I don't know if it's that easy to set up a small external board for this purpose, so I'm not sure how well it'd work... outright endorsing an RP-centered place as a sister site would work around that, but it'd be a fair bit to ask. Maybe bring it up with Gap and Nemo if people think it's worthwhile.
