Someone using the name "Alexeyroot" modified the entries about "Alexey Root" and "Dallas Chess Club" on September 14, 2009. I did NOT write (or edit) those Wikipedia entries. I was impersonated by someone using an IP address from Denton/Charter Communications. (I have Verizon in Denton). I have reported the problem to Wikipedia, and just got this response:
This user account has been blocked from further editing, but our license prevents us from changing the attribution of previous edits without the consent of the user who made the edits."
So I hope the impersonator will remove those postings, since Wikipedia cannot.
