Thanks for the compliment and welcome to the Forum, Jef! I'm glad to know that you liked what you've read so far in the Forum.
No, your English doesn't look bad at all, and even if it were, I and the rest of the Forum members normally won't be so quick to criticize or condemn its flaws. We try to be as constructive as possible with one another. What Forum members are on the lookout for are usually grammar and usage errors by mass media practitioners who strut around in print or on TV thinking that they couldn't commit any errors at all. As to people who'd really like to improve their English, I can assure you that the Forum members are on the whole very supportive.
We look forward to hearing from you often in the Forum. Cheers!
