Hello Bofahad, welcome to PC. Sorry for the late welcome.
I couldn't help noticing you welcome post here.
Well, this doesn't seem to be a welcome. It seems to me like a "Hi" & questions. To me, it's not a proper welcome.
You can say "Hi", introduce yourself, introduce new peeps to boards you like & say a "Stay cool".
That's how a welcome should be.
Well, that's all. Hope you take my advise.
