I have a BANs-style site (although using eBay editor kit) in a niche that has an active eBay community and I receive about 100+ uniques per day and have generated good buzz within the online community. I'm looking to rebuild the site to spice up the site a bit and am considering adding a forum component for users to post their own related eBay auctions and cool things they find within the niche. That said, it would be counterproductive to let them post if I couldn't tag the links they have to eBay items with my code to get commission off them. I haven't settled on a forum platform yet but I'm hoping there is an easy way to do it with freely available ones. Anybody know how to tag your users' forum post links with your affiliate code?
