Paid subscriber is an AK thing, not a VK thing. The status doesn't give any different rights or privileges here because we don't have subscriber forums.
If memory serves, there was an issue quite some time ago with a member deleting all of their posts in a popular thread, thereby making the whole thread not make sense and be almost worthless. But this is from memory.
You can edit your posts to correct the information, or delete all the information in a post, but you cannot delete the fact that you made a post. The admins can restore any and all posts in case of someone hacking an account trying to delete a member's posts, etc.
If you need something deleted, just PM any of the admins, including myself
