Pay to Upgrade thread

[WinkWay]

I saw a little mod on Webhostingtalk forums recently. When I made a new thread over there it gave me the option to pay to have that thread as a Sticky and stay at the top of the forum for X days. So the member can Pay to have this done straight away and get loads of attention to their post instead of waiting for months for people to view it and reply etc.

Thought this was a great idea for some of my particular boards in my forum. Anyone think this would be a good feature to have developed? I would love it.

Any thoughts?
