The Modx forums - my two usernames

Not sure if I am in the right subforum; apologies if I should have posted elsewhere.

Don't ask me how I did it, but I seem to have TWO usernames attached to my modx.com account. When I am the only person to have posted something in a thread, I see the username 'DutchIris' above my message. At the same time, in the sidebar I see a message that 'drdoolittle' has posted something. Which doesn't make any sense, since there is only one message in the thread so there cannot be two posters.

I recognize both these usernames since I fiddled with both of them at some point. The trouble started when the look of the forum changed (last year, early autumn??) I always used to be DutchIris. Then I did something stupid when I couldn't access my account one time. I think I made another account and then tried to merge the two or something. I really cannot remember exactly.

Anyway, I know all of this sounds completely demented but it's driving me crazy. I just want to be DutchIris and nothing else. Can anything be done about it or should I just learn to live with it?

Argh, there it is again. Please see attachment.

This has been irksome for me too... Curious if anyone has a solution.
