Sorry for the inconvenience! Are you saying the drop down for the category does not work when you click [Post New Item]? You should be able to select between Goods/Services/Housing.
You should be able to select Goods then Collectibles then Antique.
May I ask what browser you are using and what your Peerhub account name is? It's tailored for Chrome & Firefox and Safari should work. Older IE might have some issues.
Thanks!
I went back and tried again, it worked fine. Operator error probably. I use Firefox btw. I am curious how this platform will work out for the steemit community. thanks for your energy putting it together. oc
