Why can't I edit a post?

Sorry about Robin here. He's a bit ornery.

I assume the 30-minute edit rule is because people would change what they said and claim not to have said it.

Thank you for the info Videri [You must be logged in to view images. Log in or Register.].

Doctor Jeff: Thanks- I did read your post, I think I just want not clear in my response. When I wrote

"i guess I can't edit when I purchased something or if i want to change price"

I think perhaps I should have wrote:
"i guess I can't come back to edit when I purchased something or if i want to change price if it has been past 30 mins"

The rest of that paragraph was me talking aloud how i thought that was counterproductive (in that particular forum), but so be it, I will just need to make a new post if something changes and respond to all the tels in the interim that I found what i was looking for.
