People think I am a bumpkin with this name. I am, but do they think I am toothless? They sometimes think I am an idiot & call me as such just because they hadn't thought of "that" before me.

Change your profile pic, too, and go total incognito.

What's in a name? "A rose would be a rose by any other name." A name, a point of reference......

If i recall correctly you get one change. I changed mine as when signed up was blank on a name so of course I chose a hard to type out pretentious one that was a mouthful.
The pro in my case easier to log in and simpler, like me, simple creature here, vs the phrase I had stuck in my head at first.

Just do it and watch everyone either treat you like you’re new or at least try to figure it out ?
