The community server post says you should get whitelisted within 24 hours. I submitted a whitelist application a few days ago, and I haven’t been added yet (and looking at the comments of that post implies it hasn’t been updated in nearly a month). A wait period of longer than 24 hours is fine, but I think that should be reflected in the post.
Did you try messaging the server admin /u/[email protected]? He seems quite busy nowadays.
I haven’t actually. I’ll go do that now.
