Thank you for your understanding.

P.S. I don't care if you are 13. You can still read 2 pages before your post?!
Don't think I'm mean. This is a community app and 20 pages of 'not connecting.. OMG I'm so emo...' is working against community.

If someone knows what RC4 is, you'll get a superb chance to be a hero soon, so prepare.

Please get your facts right!
