Post in the right category :

When you post in these forums make sure you are posting in the right category. The forums have different categories for different topics. So find and post in the right group, so that you get the replies from the right people. And if someone else is also looking for same kind of question as you, they might find it in the right list.

Do not SPAM :

One more important thing i would like to mention is , Don’t post any self-promotion links on these sites unless necessary. Self-promotion is considered against the forum rules and you may end up getting your account banned.
