Delphi started re-arranging the pricing about four years ago, but some people were grand-fathered in for a while.
One ofthe changes was that you had to have a certain membership level to have a forum of your own. That's one of the reason the colors and all are now different here, it has reverted to a "starter" forum. No idea how long until they close it on us.
One of the women's rights forums came close to closing abruptly a couple months ago. The hostess went through some stressful "life events" and couldn't keep up with it. A man known to be openly hoistile towards women's rights came close to grabbing it, since he has friends on the Delphi staff.
