When a post is made and people contribute answers to an issue, that then becomes part of the community resource for others to benefit from. Deleting posts removes this added value. Forum topics will only be edited or deleted if they represent a valid legal, security, or safety concern.

Deleting / Editing Posts
We reserve the right to delete topics or posts that are off-topic or detrimental to the community, however it is not the general policy to edit or delete forum posts unless they are spam, harassing, illegal, or outright abuse. We will not delete your post or remove your link just because an Internet search for a term brings up the forums before your actual URLs.
Users can edit a post for up to 35 minutes from the time of submission. After that, the post can only be edited by a moderator.
