phpGroupWare Articles
Don (D.C.) Parris has started a series of articles about phpGroupWare over at Blue GNU. The articles are well written and provide a lot of good information for new users. I hope Don keeps on writing good stuff for us to link to.
The articles have also been syndicated by others which should help raise the profile of the product.
I will have another big phpGroupWare related announcement some time this month. Things are looking pretty good for the project. Stay tuned.
Update 2020: Remove and/or remove broken links.
