Technically you are allowed to post in threads as long as the information is relevant. Bumping is pointless posting to get a thread to the top of the page, not when you mvoe a thread to the top of a page and the information you've added is relevant
10 days is stupid, the forum isn't that big to warrant the idea that a thread will be on page 3 of a forum by that time :/ 14 days, or 15/20 to make a wholesome limit would be better.
