Hi Ruslan, the Italki Knowledge pages are a good start http://www.italki.com/knowledge/german

I have no specific site, but when I have to look for something I find it mostly here: http://www.canoo.net/index_en.html (short, but to my mind good) I think Wikipedia is also a good start: http://en.wikipedia.org/wiki/German_grammar there also is a link to this site: http://www.deutschseite.de/index.html
