just want to add to this thread...believe it or not I *just* found out about mojocafe.net...to my disappointment, I'm having the same problem as others...(on XP, using Firefox & IE7) I can't add any mojos, the buttons do nothing. In IE7, if I look on the bottom left, I can see a "Error on page" message. When I click it to get more information, I get this:

Line: 73
Char: 3
Error: Permission Denied
Code: 0
URL: http://www.mojocafe.net/html/mojos/m...ail.php?mui=29

(not that it's really needed, but it may help if others can confirm this on other OS/browser configurations)
