Don't see anything wrong or suspicious on this point. I have different names on different forums but have no ulterior motive for it. On some forums if you don't log in for a long time you may need to re-register and then may find the old user name or password is not accepted as it's already taken so you have to come up with something else. I started as Steve1903 on all forums but now Captain Kirk on GB's board and Tiktak elsewhere. Means nothing, doesn't make one a troll.
