Most forum's do forbid this kind of behavior under their terms of use, as others have noted here. Keep in mind that they could simply disable the persons account which could make her even more angry.

What you are looking to do would be defensible if there is another use of the name beyond the school mascot. For instance, a high school might be 'wolverines.' Michigan is also the wolverine state. There are dozens of companies in Michigan using the name Wolverine. But none would likely involve, for instance, selling University of Michigan football memorabilia. Many team names are common words with lots of trademark uses beyond the team use. The other posts are correct. The issue is...

The practical issue you face is whether you can (a) afford to re-brand or (2) afford to fight them off with a response letter which put's your best foot forward. Often times, a well drafted response letter from a trademark attorney will stop further threats. While you have to pay an attorney fee to have such a response to their threat letter drafted, it...
There is a split of authority as to whether the statue of limitations for copyright infringement is one that is always tricky. You may have some relief if the infringement is continuing (which you suggest may have ceased in Dec, 2006). Even so, you may have until December, 2009 to file, the date of the last infringing act.
