I started a reply earlier saying I didn’t think we had one yet, but couldn’t quite find the words to convey that whilst also not sounding like I was volunteering to write one… 
But no, I think it would be good to have one. 
I’ll add it to my list. 
I think with support being set to ‘low’ it automatically elevates all the others, so this may not be necessary. 
I’m wondering if searching for something that existed would give better hits?
Instant update: No, no it does not. I tried ‘invites’ and ‘whispers’ and got more feature and bug topics than Documentation. Let me give that a little tweak and see if it makes a difference.
