It difficult to leave a message when 1800notes keep stopping the page as you write,to make sure you get all the advertising,one at a time!  BTW this number also calls and never levels a message!

I have no problems, although sometimes page loads stall.
How old is your computer? How slow is your Internet service?
You should write your post in a text editor, save it, then copy-and-paste to the "Message" box on a webpage, especially for long posts. And also copy the link into your text editor.
That way you will have an offline record of the entire post.
