I just want to remove all friends and people, how? including the ones on the minibar below my screen

You can remove a friend by going to the users profile & clicking "Remove Friend", which is right above "Send Message".

If you still see the friends on the minibar below where it says "Who's Online" here is how to remove them

Social > Inbox > Contacts

Select contacts, then at the bottom click on Remove Contact

So.... deleted all the contacts... uh... still can see them in the minibar... and is there a way to see all the ppl that i received and allowed friend requests?

The names in the commet chat are there because those players have accepted your friend request, removing them on your end will not make them go away.

As long as you hadnt deleted them from your contact list you will be able to see contact (players who's sent you a fried request that you accepted), friends (they also have you on their list) and others thing like that. Once removed there are no archive as far as i am aware.

Thanks!
