The rules here are fairly simple.
1. Be familiar with the MSN Code of Conduct, and stick to it. By joining this group, you have already agreed to abide by both this and the MSN Terms of Use.
2. Please note that a site nickname must begin with a letter and can be composed of letters, numbers, the underscore, and some symbols but it cannot contain any of the following symbols:
! @ # $ % * ( ) + = » ” ; : . , < > ? & /
Due to a programming artifact going back to the dark ages of DOS, these characters can mess up the site beyond belief.
That's it. If you're wondering about flaming, spam, copyright infringement, advertising and all the other typical rules, they're all covered in the MSN Code of Conduct. If you haven't read it yet, please get to it.
