I try to avoid these if I can cause I find describing myself awkward. I’ve already been talking here for a while, and only just remembered I have to do this to get verified 
Fun fact, my pfp is a fan regeneration I made of the Meddling Monk, based on the musical artist professor elemental. That probably says a lot about me alone…
Hey, been nice having you around!!
Nice to have you here!
No need to make it awkward, I’ll describe you so you don’t have to do it yourself.
The1_Foxy is cool. I mean Cool with a capital C, Cool to the point of total awesomeness. Oh, and taste in TV shows? The1_Foxy has impeccable taste, particularly in sci-fi entertainment. The1_Foxy totally rocks.
If you don’t feel that description is comprehensive enough, feel free to add any details I missed.
You’ve been around for a while but you’re nonetheless welcome!
