Guys, I am not saying that the site is unhelpful - I can see that everybody is very committed, there is great feeling of community, and I definitely did NOT aspire to sound rude or offensive!
Nevertheless, I feel that it is extremely important that the content of such sites is proofread - especially because most people accessing it need extra help with their English, this site should provide excellent level of standard English so that not to confuse anybody; e.g. "resince" instead of "residence" would have confused me some years ago! You may not agree with me but it is my point of view...
By the way, I am not a citizen yet - passed my test yesterday. I have been in the UK for 4 years and I am teaching English and IT to English students at the moment. Believe me, they make horrible spelling mistakes all the time; but I think that we, as foreigners, are under worse scrutiny and should strive for perfection.
