I once registered in an English-language thematic social network with one purpose - to train the language: I thought I would make a bunch of mistakes there in the posts, people will rush, scare me from legs to heads, but they will point to all the chicks (well, the type - chicken is dumb, children know that there is an undetermined item here). And they are there, all the fools, thank you for sharing! I like it! and etc.
What do you do, I think I will never learn English like that.
That is the case on our websites - there I was regularly told how low my level of knowledge of Russian:))
