My experience was pathetic. They were very pushy and were always calling (still are to this day and this was almost a year ago).
They call me asking for a credit to publish my book that I told them I no longer wanted published. They kept offering me free classes to get over writers block (if I supplied my credit card of course).
Also, they call you about 5 times a day, so if you like to to feel important then have fun, but i'm not one of those people. The phone calls have gotten so bad I had to block them.
