MyBB Codes

So here is something I would think could be pretty useful. On my forums, I have themes setup for each of the holidays. What I would like to have is a plugin that can automatically change the theme based on the date. Looking at the themes themselves, looks like each has its own ID number. So my thoughts are to have a plugin that is similar to this.

Auto Theme Changer
Theme ID Start Date End Date
24 1/1/10 1/2/10 - New Years Theme
15 12/20/10 12/26/10 - Christmas Theme


so on and so forth.

Possible/interested?

It sounds an interesting idea. Maybe other coders would take it up cos I won''t be creating any new plugins atm due to my free time being very limited.
