I'd like to add the following remark to this for more clarity. It is done from my experience, gained here during 4 month, while I've been at this forum:
Most of people here are not aggressive and not resentful, so they will likely not say anything rude to you (at least, intentionally) until you don't irritate them.
- If you'll irritate or offend someone accidentally, they will likely explain what are you doing wrong in polite way. So you'll understand this and evertything will be ok; you may not to be affraid to say something wrong unintentionally, it will not lead to catastrophe of any sort.
- If by the chance somebody will offend you in any way, you can explain it calmly as well, and the person will likely apologize and will keep in mind what they shouldn't say such a things to you again. If they would continue to be offensive (which is unlikely, but still), they will have a time to think about their behavior in temporary ban.
According to my observations so far, the problems are arising only in people who ignore reaction of others for too long and continue doing annoying things after several clear explanations. So if you pay attention for others words and try to be respectful for them, everything should be ok and you shouldn't have any problems.
