PHPGTK-Inlook should be, when finished a small business solution and alternative for MS Outlook and MS Exchange Server because this software is too expensive for small business firms.I want to program a program which looks like Ms Outlook with the same functions :
It should be possible to share the contacts and the schedule to other users on a network. To provide this the schedule and contact data will be storaged in a mysql Database or something similar like OpenLDAP or MSSQL etc. ...
The program should be programmed in PHP with the extension GTK++ GTK stands for Gimp Toolkit and was ported for php, you can find more about this on http://gtk.php.net and over Gtk on http://www.gtk.org
I hope I had answered all your question and hope that you will join the project.
