I talked to the guys at Wix about your complaints a long time ago, so I wonder how many of the things we wish we could have seen improved have improved and which have not.
With what you tell me again, I will send you a message and I myself will try to improve as much as I can.
I know a couple of folks have not been able to change their user names, Doc Oboogie for one.
The only thing I have really found tricky is the private/personal messages. It isn't a big deal as I have several people's emails, which I can use instead.
The notification seems to be sorted and I cant think of any other issues EXCEPT YOU ARE STILL PAYING FOR IT!
