Hello and welcome to the forums. Joining an english speaking forum will help your language alot, even if you do have to use a dictionary most of the time [oo-er that's probably a hard sentence to understand >_<].
This is an English speaking forum, and as lovely as it is that you're all sharing your multi-lingual abilities, there is a rule to keep all chat in English. You can talk in whatever language you want in PMs though.
So yes, english please.
Other than that I hope you enjoy it here.
