I don't know how to mark this as abusive spam, but someone should delete this post or at least remove those links immediately. NOONE CLICK THOSE LINKS. You will leave Geni and go somewhere potentially very harmful to your computer.
Thank you for your warning not to click the spam hyperlinks.
Under every post -- on the left -- is a "report" hyper link with a drop down box. You can then select a reason from the drop down box and add a comment.
When I did that for post http://www.geni.com/discussions/93409?msg=693209 I got the message "already reported." Geni customer service will take care of it from here.
I see it now! Thanks!
