Hey there- I’m a newbie too, welcome to the site! I’ve been trying to sell on MUPS and while it’s slow going getting set up and recognized, at least people there are serious about panty selling and buying. So it’s totally worth the money to set it up.
Craigslist was something I tried for a few days before I discovered Panty Hog and from my limited experience, most of the people who replied to my ads just wanted free nudie pics. Or worse, they wanted a prostitute. Neither of which have anything to do with panty fetishes, so I kinda gave up on that. Maybe someone here has had better luck that could advise though?
Definitely check out the Ask Serena articles, I read through all of them and they were super super helpful.
Welcome again hon! Glad to see other newbs around.
