@Vikas Maybe you could ask in the Assembly. That is the room recommended here: How do I unfreeze a frozen chat room?

Another alternative could be to ask mods from your site. (Perhaps by flagging some post and explaining in the flag wha you need from them..)

@MartinSleziak Do I need to tag someone in Assembly?

@Vikas I'd guess usually people simply post a request there.

If mods from your site are active in some chatroom there, asking one of them might be a faster way to get the room unfrozen.

@MartinSleziak Mods there aren't cooperating. I flagged a message and requested same.
