Note - just switched from Chrome to Firefox because the post above was apparently not accepted. That is, still sitting with the text box and a "Post Reply" green button. When the button is pressed a black(ish) area near the top right of the screen shows some kind of shimmer for a while, then disappears. The progress indicator on the top tool bar (an X to stop an action or a loop to reload) doesn't do anything.
This PC has sufficient processors and memory to handle most stuff. My Internet connection is pretty fast. Therefore server problem(s).
I can see the post on here, but the site is currently going like a dog.
