Multiple Accounts / One Account Per PC Rule
- Multiple accounts are not allowed!
- There may be only one player per computer.
- Using the same internet connection is not a problem.
If Mr Shadow notices that at any time that more than one account is being used on the same computer (except during holiday cover) then he reserves the right to close one or both accounts without prior warning. More normally, you will get a PM from him first.
