I really am not on the wikimedia stuff much, and when I was, it was strictly on wikibooks. Here is my page there:
https://en.wikibooks.org/wiki/User:RobKohr
You can contact me here, there, or on my gmail account which happens to use the same username as I use here, or you can even contact me on facebook http://fb.com/constantsun
I also run http://editthis.info where you can create your own wiki in seconds.
