There is an evern more obvious reason why you are not allowed to delete your own posts. It forces you to think before you speak.
If it is the case that you have posted something on this forum that you want to now delete, that tells people that you were saying things that were illconceived and probably that you're just trying to make yourself look better.
There is a genuine edit time for accidental, heat of the moment changes, however anything you post onto this site is a matter of public record. It is freely searchable by anyone and any search engine and it will not go away any time soon.
Having said that, we aren't without caring, and if there is a genuine slip up that has gone through and the edit timer has elapsed then the section moderator I am sure will help you; just not for ego reasons
