Ok, here is my go on correcting your entry =) I wrote the corrections in black. I'm very impressed, specially because your language has so little in common with English. Probably you already know this, but if you write English in a formal way, you shouldn't shorten/abbreviate the verbs. This entry, anyway, did not look very formal to me ;-)  

What is this?

Hi, since I'm new in to this community, I'm gonna ask a few questions here. Mostly about world domination, drugs and porn stuff. Just kidding (actually the porn part is a little bit from the heart).

Q:
- How do I start to use (this isn't wrong, but I'd suggest '' how do I start using'') this website properly?
- How do you see other users' "thing" (this is totally about their activity, not their junk, you pervert)? or whatever it is called in on this website.
- To whom do you ask questions?
- Is anybody whom which who (this rule is fixed, ''anybody who'') I do not follow ,or not following me, can see my notebook/questions?
- Is there anything like status or something like other social networks? (''other'' refers in this case to a plural form) 

A:
How about you go try and explore it yourself, you newfagtard! Some of your questions even had the appropriate answers when you wrote this note. You're welcome.

Gee.. chill out, man. Something is wrong with your manner, muscleman. /
Oh yeah? well then something is  wrong with your head, newfagtard! /
HEY! DON'T YOU DARE CALL ME WITH THAT NAME EVER AGAIN!! I HAVE A NAME, y'know. You're just overreacting. /
Oh yeah? What is it? NewFagtard DickinSon bin GayLord ButtHurt? /
You ask for it, man. Don't blame me for what will happen to you. /
Yeah, this is what I'm waiting for, kid. I'll wait for you outside of this room and let's finish what we've started. /
You're the one who started this unnecessary fight but it's fine with me. Let's do our business *door slammed*
