Generally:
1: Be respectful and polite!
2: If you have a bad day, don't bother your fellow users with your anger.
3: Chatting is fun, part of fun is humour. But remember, not everybody has the same sense of humour. So something you may find very funny could be offending for someone else. So don't push it to the limits.
4: CAPITAL LETTERS, bold characters and smileys/emoticons are only to be used to highlight something. If you exaggerate using them, it will be considered as spam.
5: Four-letter-words, glorification of violence or drugs, pornographic contents, racism etc. are not tolerated in the chat-rooms - users who don't follow these rules will be banned.
Help:
1: Help new users. Remember your own beginnings here; certainly people were helping you then.
2: If you have questions about the chat, just address a chat mod or an admin.
Advertising:
1: Don't post any links of active auctions (yours or those of other users). Advertising is not allowed. Exception: The room "Transfermarkt" (transfer market).
2: No commercials for other online-games.
3: If you don't follow these rules, you will be kicked - if this doesn't help, it may also result in banishment (chat/forum).
Spam:
1: No spam please (avoid chains of smileys, nonsense chains of words and stuff like that).
Shout box:
The rules of the chat also apply for the shout box - especially: No links of active auctions.
