Here are some possibilities of Communication...
1.) Forum 2.) Chat 3.) E-Mail to Clan leader
Please use forum for topics, which are concerned on the game, e.g. a member cheated or you want to sell a good item etc. Stupid messages will be deleted immediately.
You can use the chat for everything. Soon there will be some meetings, which take place in the chat. You can write everything you want, unless other chatters are disturbed from it. At the moment everyone can enter the chat room, but soon I'll change that.
Send me an E-Mail if you have got a (technical) question, which doesn't fit into the forum, or you don't want to publish it there.
