I posted about it at Twitter, though very briefly, but I can now officially say I’ve used Word Press for work purposes.
They wanted a private site where people could share information and categorize it. Not exactly a forum, since people would only need to post about once a day at most. Comments weren’t a requirement but a nice plus. I figured Word Press would work for this and installed it. I just finished setting everything up and it works. I basically got a description of what they needed and was left to figure out what to use myself. Cherri initially introduced me to Word Press and Adri made me give it a second look, which later got me to use it more.
