At last something that works pretty well under firefox and with multiple selection possible (using Mootools HtmlTable.Select). There are some problems with IE and Chrome (the position: relative on td elements is not well supported).
Mootools update (1.3)
close#109
Checking limit when creating/updating a mailbox.
Work in progress:
* New domains admin page, all menus are now at the same level,
* Views, models and forms partial refactoring (better code organization).
Querysets used to populate form fields are more filtered (ie. the default admin is ignored, as the current logged in user).
see #92
More protection against errors that can happen when defining new permissions.
Work in progress. Multi selection is working (using shift+click) but I've made a mistake somewhere because the default shift key behaviour is not working anymore.
