It is not allowed to promote yourself or your company in this forum, so you can't put your URL or the name of your affiliate program in your posts. However, you can put your URL in your profile. This way anyone who is interested in your program can find your website. If people ask you for information you can also send them a sticky to promote your program. I think you are allowed to post a few more details about your program. (not too many specifics) If you just tell us the kind of niche you're in and who can join the program (international webmasters?) I think the mods will leave the message on the board. But since I am just a user of this forum, I can not tell your for sure. Just send one of the mods a sticky to find out what is allowed...
>>I am particularly interested in "places where to find" affiliates.
You'll have to do some manual work to contact those sites/affiliates that can be of direct benefit to both of your sites.
It's nice to be listed on a bunch of affiliate program directories ( this is also a search you should do and post your program details there), but to reach affiliates who can immediately start to make sales for you, you'll need to contact them.
