confixx like all web panels has good and bad points, it's not as intuitive as say cpanel and it uses the 'user' system for hosting, so you add a user, then a domain for the user.
But it has about the smallest footprint of all control panels when it comes to resource use and has some nice built in features such as the international character domain names and @domains and can be customized quite easily.
It's a steep learning curve but once you have got to grips with the way it works it's pretty good.
All kind of problems, it had too many bugs and the support was useless. They promised updates for a long time but nothing happened. For the moment we even get an error when we try to add a new user(not that we need to do it...)
