I need a new wiki site:
1) open source or relatively inexpensive (<$150) wiki solution
2) WYSIWYG page creation/updating for users and admin
3) page templates possible (user input is structured according to a standard format)
4) easy design management (such as Wordpress type theme solution) and page configuration
5) custom search function on main page to find inner pages according to a drop-down menu selection
That is about it...more details can be communicated on PMB.
This is a serious project and I will put some money into making it good.
