On Subscription chose random group

[dcdub]

Hey im looking for a hack for 3.5.2 that would when a member subscribes to one of 3 subscription terms.

3 Months
6 Months
1 Year

It would give the user the option of selecting the user group from a list they wish to enter, or if the "no prefrence" box was checked it would place that member in one of the usergroups by random, The random selection would be based on the usergroup with the lowest user count. Also an admin function whereby you can disable certain groups at certain time

i dont think this would be a difficult hack but im strugling to get my head around it

if you want to help and know more about what im after either reply to this thread or msn me at alex@whosyourhost.com

Thanks
