As Hiidoran, the friendly one, has given you a lot of information, I'll just go along with the stuff I can XDD -shot'd-
Howdy Mucus! Welcome to PC, the only place you'll ever need for both Pokémon and a bucketload of other topics :3
Wow a photographer! : D We don't have many photographers here, so you're gonna go down a treat. Everyone'll gasping for your work, believe me. Ooh, and you're a whiz on Photoshop. Well, PC can never have too many of those.
If you ever feel you can make graphics for the people around PC - maybe you have a time off or something, that's a common one ^^ - then you could set up a shop. Though before doing that I would check out previous ones, so you can get a feel as to what to put in them :3
It's lovely that you take your relatinships seriously. Although most of us are friends on PC - yes, there are the occasional couple XD - we take those relationships very seriously too. And once you've got a friendship on here, it'll very difficult to lose it ^w^
Ach, don't worry about embarrassing yourself! -
I'm exactly the same XDD
And if you make a mistake or do embarrass yourself, someone will most probably tell you and remind you! You might wanna read the FAQ as well as the Community Rules, as it has some more information.
I hope you have a lot of fun here, make some friends and have an enjoyable stay!
