Another remark:
What if users would like to see mestakes made by others and also see corrections. It may be usefull for them (at least for me).

And, by the way, whay do you write either in Russian and in English? I suppose all of RF-users can understand English speach (or texst).

I've got an idea: those who arn't Russian natives but can write in Russian quite well should write in Russian; Russians should write in English. It'll help us to improve our capacity in foreign language.
So what d'you say?
