Giveaway Key after 10 posts

[Hobbit Stomper]

Hi there,

I am running a forum and I have acquired several 100 cd keys from a publisher as a promotion for a pc game.

The goal is to give away those keys to all users who have at least 10 posts or more. Because of the amount of keys we can give away, we can not manually do this.

Is there a modification that could be used for something like this?

My basic idea would be to upload those several 100 keys to the database, have a function in the user control panel that users have access to if they have 10 posts or more, where they can fetch a key. That key would then be marked as used and will only be displayed to that specific user who it was assigned to.
