Erm, how would it be a problem? It's not you that would need to go
here as you seem to understand English....to an extent. They are dedicated pages to their native languages. Note underneath all those languages it says: Translators needed. Some people understand English and some don't. Some understand a little and some don't.
and the directions on how to use mirc arent that complicated to understand in english
This might be the case for you but as I said there will be a number of people in which it isn't the case. Hence why sometimes people write here in their native language and usually use a translator to see what people reply back to them.
