Yes, but the thing is...if you have an edit button available at all times, people can go and retract their statements at the first page in a 20 page thread. With 5 minutes, they won't be able to retract their statement that started the whole mess. They may however, be able to retract another idiotic statement they made on say, page 8 because it was only 5 minutes prior. I don't think 5 minutes is really going to make or break anybody here on the forum. Usually if you want to delete/edit a post that is starting a lot of shit, it usually comes with a huge arguement afterwords, so the 5 minute thing could apply to the whole forum I guess.
