How come on this website you only give a little bit of time to correct stuff

There a two hour grace period to be able to edit your posts by clicking on the icon on right hand bottom corner with the folder and eraser on it. Members should try to limit multiple posts that continue one after the other without any response in between and edit the posts instead.

The reason why editing is limited to two hours is because editing or deleting posts can destroy the quality of the discussions in the forums. Before this policy was implemented someone decided to delete all their posts and those discussions needed to be edited extensively or deleted. After the two hours period, if you feel you need to urgently change or delete a post please contact us and we can help you to deal with the problem.
