I had trouble posting with my Ipad when I was out of town but no problem from the computer. Don't have any idea why.

It seems to be very inconsistent in behavior. I struggled a bit with comments but thought, like ArchVanBelle that it was just me

I have learned that when it will not post if you will touch the back arrow in the upper left corner, then immediately touch the forward arrow it will go right back to your comment, then hit post, it will post.

Here *I thought It was my Parkinson's that was making do funny things on this site. I have been typing on this site And forget to save my work and it all disappears. ATfirst I thought it was because I tend to be long-winded.Then you back and try to make changes everything will freeze on you.

Let admin know every time it happens to you. I did and it happens only once in a while that I can't post.
