I locked down the old community forums as dealing with 99% spam posts there is not a fun way to spend my time. Please use these new forums here instead.
We probably need to talk to the LibreGameWiki people if they still want some sort of forum? I guess most of their coordination happens in the chat and on the wiki discussion tabs?
As for other hosted forums. Please get in contact with me to discuss the way forward. I'll keep the old forum sections open for now as long as they are actively moderated and will check for first post approvals from time to time, but this is not a long term sustainable situation.
