Now I tend to take very little seriously, so I have interpreted the "caste system" as kind of telling everyone how much time we spend on the board when we could be quilting!
There are some things I like about the board and some I'm not crazy about. I'd like to see the entire original message at the top of the thread, and the list of responses below it.
I'd like a lot less 'mousing', as 'mousing' kills my right arm. I've tried 'mousing' with the left, very clumsy, and ultimately, I have the same problem.
If the message is strung out so much that you have to scroll horizontally, then try 'control l' to shrink the screen.
I like having the ability to format my responses (not that i do), and change the font to one that is easier for me to read.
