I've almost never changed mine and even when I do, its usually just a gimmicky form of my current username. XD

I guess that it's to start "fresh" in the forums or just for fun, idk really. I'm guilty of changing mines too because it feel like my one alias wasn't cutting it enough or may of offend someone in the past. If you ever need to reference a previous username for an user, you can always check out the their "display name history" right below their Brohoofs counter.

Yeah! D:< I can't believe some people would do that! Some people , am I right?

*raises eyebrow* Riiiiiiight.

I've changed mine...  Thrice.  Over the course of two years (and change).  I get what you're saying, though.  I'll run across someone on the forums who I don't recognize, only to realize (after taking a peek at their name change history) that I either like or dislike them. xD  How am I supposed to know who I do or don't get along with if you change your names?2?3!?

Even I am guilty of changing my name, but I always keep part of my original from now. And mention who I was in my sig. But then I meet friends I don't recognise with their way different name. And the only way I know is by the history. Although I have theories on the name changes, I continues calling certain  friends by their old name, because thats how I know them. Although it may annoy the heck out of them... :/

I started out as 'Leafy' but a week later I was 'Icy Wind.' After like, 5 months, I was Fire Twii. And I plan on keeping a similarr name for a while.
