Well I guess that forum rules appears as soon as someone does something that not are liked by other users/admins.
and cause this forum is young so would there take a little bit for the spammers to come,
as it is now, there is no need for Forum rules, but times are changing.
A few
1- No double post, basicly this reduces the spammers. and users that only want to increase theirs post counts and so on
2- No bumping, a topic that are old are also dead.
3- No harm to other members, this one is one of the most obvisius and means that you aren't allowed to say anything bad to another member.
4- No double acounts, this one is normal on other forums, but I can't belive why anyone would have 2 acounts?!
5- something like avvatars and signatures rules? Maximum sizes and file formats jpg, gif etc etc
I am new here and trying to help, and I am sorry for my bad english but I am trying to make it better
