I do consulting on implementation, optimization, and maintenance of tikiwiki for various for-profit and non-profit organizations. Some of the public sites that I have developed are TWIST Standards, an international financial standards organization and the Advanced Message Queuing Protocol group.
I dabble all over, implementing, bug fixing, creating modules, refining templates and features, and setting up multitikis on a contract basis.
I live in the San Francisco area and can be reached at: tikiwiki (at) garygriffin (dot) net
I created a wiki plugin for displaying Windows Media Player files. It works for IE and FF browsers on 1.9.x versions. Download the attached file and place it in lib/wiki-plugins/ folder to make it available.
