I have a question: I've been trying for a year now to improve my English because my work and my studies require me to understand the language. I think I do pretty well right now and the forum helps as well. However I have a problem with longer sentences especially in written English since I don't really understand the punctuation rules. But I want to post in this forum with correct grammar which also includes the punctuation of course. If you have some valuable tips on that matter I would be very grateful.
