I operate a site called Coopling (www.coopling.com). Joomla 1.6.1, CB 1.4, CB Subs 1.2.1.

I'd like to know if there is a way that I can limit the number of PMS or emails one membership class can send per month to the other. This would be much like LinkedIn's InMail feature. The limit would be 5 per month. At the beginning of the next month, the number would reset to 5.

My intent is to foster communications but not enable spam or abuse by members.

Thanks
