"I jealous for what" is bad English no matter who you ask

Native English speakers also make grammatical mistakes. Please be reminded that there are literates in developed countries as well who don't even know how to spell so it's important whom you learn your English from. BTW, i wasn't even among those who made suggestions if you checked properly. However you appeared to be a bit rude by using a banner like that. I simply wanted to point that out to you. I'm sorry but someone has to tell you the bad news. In terms of knowledge and experience in COMPUTING(you mistakenly used computer), we can tell that you're not superior anyway.
