I had that problem yesterday evening. I would start typing a comment and it ran on and on never dropping to a second line. Then it would not post when I clicked on Submit. No problems this morning. I was finally able to post one comment but not the other.

I went to the very long list of topics on Garden Web, scrolled down and down, found Kitchen Table and used that. It worked, but as my father used to say, " it was the long way around the barn."

I use this as my shortcut:

https://www.gardenweb.com/discussions/kitchentable

Click on this link, then you can bookmark it for future use.

When I try to type in kitchen table as where to post I get this:

Kkitkit

When I erase it just adds on. Learned I have to backspace one letter at a time

It sounds like you are on the houzz Url not the gardenweb url. Look up at the address bar you want this

https://www.gardenweb.com/discussions/5931602/why-can-t-i-post-on-kitchen-table#n=5

Not http://www.houzz

Just click on the link I provided. It's my saved bookmark. Brings me directly to the KT every time. Save it for your own bookmark and you'll not have any trouble getting to the KT.
