We have MarketPress installed on our site, that has a Etsy/Blog style to it. We would love to be able to get stats on who in on our mulitsite site is the highest seller to be able to give awards, recognition etc... Plus we would like to get stats to now how much we are making from the commissions we are getting with each sale they make. I have not found those options anywhere on the site. Is there a reporting area, stats plugin something that will give me these things?
