After you've been here at least a couple of weeks, posted at least 10 times, and/or you've successfully supported another partner's launch (you've made sales, that is), and you have an upcoming product launch of your own ... consider requesting a premium announcement.
In the meantime, post and respond to gain exposure and credibility (don't forget to create a sig file, the only form of self promotion in the General Discussion Forum allowed), and feel free to submit JV Marketing related articles to perpetuate the process even more.
