Report a private message?

[Alaric]

I got a private message that I believe was an advertisement, where do I report it?

[tamoneya]

just forward it to a moderator.

Forward it to the staff. That's the best we can do at the moment.

All the same, there was a spate of PM advertisements recently, and the offenders have been banned. It is likely that whoever sent this to you has already been dealt with.
