This new forum format is a case of breaking something that is not broken.
Here is what I have found that either has problems or I do not like.
#1 Its incredibly slow to refresh.
#2 The left and right sides of the screen takes up valuable real estate for those of us that keep multiple windows open.
#3 The size of the postings takes up too much room in the middle.
#4 I have had many messages that the database cannot be accessed.
#5 When I did a preview, not only did it no preview, but it wiped out what I had typed.
