You're right we did suppress the option to "solve" posts if you're the original poster and indeed this was to prevent point hoarding.
I'll speak with our application team and see if we can null the value if the original poster solves a his/her post. If not I we can probably add an option for self solved.
When we have something put together I will reply back to on this thread notifying you of the change.
thanks for the feedback it is appreciated.
