Hi Julie,
Not the most elementary question at all. Never be afraid to ask.
Looks like you figured it out! But, for others wondering the same thing here is an easy way...
Login to your GDI member area.
https://www.website.ws/members/index.dhtmlClick on "My Replicated Sites" in the left menu of links. You see all of your affiliate pages there.
Now, right click on the one you want, choose copy link or copy link location (depends on your browser) and now you can paste it into your blog or website or widget or whatever.
Easy peasy! Hope that helps.
Vince
