OK so not to jump into any argument here but I think I should point out a couple things.
1) There is a modify button that allows you to go back and change what you said without creating a whole new post. This little feature is highly useful to avoid posting 3 to 4 times in a row.
2) Bumping a thread is typically not used until after a 24 hour period. Thirty minutes isn't giving the people who need to see this thread the right amount of time.
Just saying.
