On the main page you'll notice:
...Witamy na stronie poświęconej nauce języka angielskiego. Znajdziesz tutaj wszystkie potrzebne informacje o egzaminach organizowanych przez British Council, gramatykę, ćwiczenia i testy online, forum dyskusyjne i dużo dużo więcej...
The problem is that (and I know this is so hard to believe) many of us have full time jobs, family, children and one thousand and one other responsibilities. So whilst talking, when you have nothing else to do is absolutely wonderful - most of us are chasing our tails for lack of time. People devote their time willingly on this forum for the purpose of passing on their knowledge (based on years and years of experience) to others who need help.
As for other forums - I'm sure that if you search hard enough you'll find something.
