suggestions

As the title says, clan owners or high ranks need to send mass messages to all the clan members and this would be a nice feature to clan system

The post office was built specifically for bot-to-bot messaging and would require a pretty large rewrite to support multibot messaging, so this won't be happening for awhile if it does happen.

i think this was in bots2, would be cool to see again,

Using the clan forum should suffice. Clan wide messages were cool, but not necessary.

I agree with Badgerman, with at the max 20 members surely it can't be that hard

Also I for one don't want any messages from Jans saying "get more CS clan" or it's bots4 equivalent.

Were you in his clan in the beta? He did it anyway, manually lol. He even put [Clanwide msg] at the start of it too.

Damn straight. I dont need no 'mail everyone' link.

Forum will do
