That Supporter week would be such a tease, that for one week your players would have uniform numbers... I could see how this would be a nice little promotion of Supporter features. New managers can't fully appreciate them, but anyone who's been around for a few seasons would understand the difference between Supporter and non-Supporter better, and for that one week, it could be an opportunity to attract a few more Supporters.
I don't think giving teams money is worth even discussing, though. Get a job! ;-)
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
