Selecting the Right Venue for Your Private Ad One of the very first things to consider is what venue you’d like to use for your private ad. Do you want to write a private ad and postbode it on a webstek such spil Craigslist.com? You could do that for free but be sure to understand that anyone can postbode or react on Craigslist without much “filtering” of the ads, so please be cautious.
