I don't mean to double-post, but I can't edit my original question or subject & I got five replies from people who thought I was looking for cheap ways, like posting my links in my signature on other sites' forums. I'm looking for the best type of free forum that I can use on my own site (for me and my users to post on). By "best," I mean, which one gets indexed faster in google? Also, it has to be coded in PHP. On average, how long does it take to get posts indexed? Also, is there a pinging service for forums, just as there is for blogs? Thanks.
