Yep - if you click the little :!: button on the bottom of the post there is an option to report - then any moderator will see it - I don't know what you guys see, but I get a little flag on any area that has a reported post.
A PM on top of that doesn't hurt, but if you also flag it then other folks will know it's already been reported and I won't get 20 PM's about the same spam account.
Thanks everybody for helping to keep our boards free of crap... well, crap from people we don't know LOL.
