I have been using Wikipedia for several years and became interested in the minor editing/proofreading aspects of the project(s). My personality profile tends to lend itself toward that sort of work.
Until I can get a handle on article creation, and due to my busy life, it'll be a while before I'll have any articles composed or to be able to participate in any of the Wikiprojects.
Retired from government service 31 Jan 2013. Been busy ever since.
