I don't think a DM function would be a good idea... people (myself included once or twice probably lol) might send some nasty messages to people they just wiped the floor with hahaha.
I've been trying to get my guild mates to post on Hive, had some success so far!
hahaha, what's wrong with a bit of banter? Maybe even limited to referrals then. It's in your best interest to help each other instead of just scolding each other. Add a block function and it should be snowflake proof :-)
Lol I know the benefits of the chat far outweigh the little drama that will happen. One thing I hope we don’t see, and maybe there can be rules against it, is spamming and malicious people stealing (or trying to) keys and stuff.
