On the main page it will say start a conversation. ..click it. Than type in your subject which must be 15 or more letters...than type in the body of your message than click next...here you must choose at least one place for your thread to goto. I scrolled down and found kitchen table and clicked it..than I clicked post. ..do not assume that just brcause your at the KT when you start your thread that it will show up here...it won't unless you choose the KT.

Yay it worked after numerous tries!

Answer for me on my device is NO. From Home Dec Convo,, there is no option given tho crosspost to either The Kitchen Table (TKT) or Cooking. Some members cannot access TKT or Cooking to post. “Other” forum can be x-posted to from Home Dec Convo and it is bi-directional. We could Move TKT to OTHER or take over The East Patagonia Pogie Fishing Forum. Just Houzz runing things here?
