- Not as customizable
- Themes difficult to make with use of stupid TPL files
- PHP errors numerous and difficult to handle because of poor and sloppy code with loop holes
- Almost a hundred MySQL tables to sort through
- Slow and image-happy
- Fast but often not helpful support
- Software Home Page Contains Links to Remote Files
- Plugins usually made by professionals only
- Difficult to integrate with CMS
- "Their own type of PHP code with strange variables"
- Heavy but Attractive but also insufficient (not all links are showed in navigation and portal just plain ugly)
