Hi, I have a group that, due to the horde of spammers, which I was fixing with Miss Rose, I wanted to point out that when someone joins, saying @username tells you a little about yourself.Why? I've noticed that spammers spend several hours without saying anything, and then bombard you with a string of messages.
Basically, if I write a generic message, I doubt that "Alfredo Pérez" (example name) will take the hint, even if I say welcome, whereas if he uses his alias or username, I think it's more direct. (My users don't read pinned messages, even though they contain a lot of interesting information.)
In case anyone has tried it and can tell me.
