I prefer email first because everything is in one place. If you're talking about a forum format not on ABW
but on your own site, just don't have the time for it. Of course i have hundreds of merchants but maybe for some affiliates that only work with a select few and maybe your bigger affiliates. Blogs, I have a growing list of merchant blog urls but it's usually the same stuff i get in emails. Maybe send out an email and ask your current affiiates what they prefer. As long as merchants keep sending out affiliate emails, I'm good, that's all i need.
