Is there any interest in having a discord for the clash speedrun page, probably ran by a moderator? Currently there is not a centralized place to chat about speedruns, discuss strategy, etc.

I think the forums here are fine for discussing things, I don't really see there being super frequent discussion about anything so there's really no need for one to be honest. If somebody wants to start one themselves they can go right ahead, but I don't think any of the mods will do it.
