Just a note to let everyone know that I am moving the articles from the reference library to the Wiki where they can be better managed and updated. So for those of you who browse these area's you may see some duplication and differences between articles. Should there be a difference between articles during this change then the Wiki version should be considered the current up-to-date version.

Anyone who would like to volunteer their services to help on the Wiki staff are welcome to contact me.
