from http://webdiplomacy.net/rules.php:
•Email the moderators at
[email protected], not their personal addresses.
What to send
•If reporting a multi-accounter:
◦Links to the accounts of the players who you suspect. (If reporting via email)
◦Link(s) to any specific game(s) that raised your suspicions.
◦Any relevant information that you have noticed.
◦You do not have to tell us who you are, but it can be helpful. (If reporting via email)
◦If reporting via email please make the subject line more useful than "multis?" Something like "Multis: Username1 and Username2?" is more helpful for the moderators!
