I am the original developer of TrinityManager, a great CMS from ages ago. I have been stagnent for many years, but have been considering building a new CMS to use side by side with TrinityCore (and perhaps even as an addition to the main core) using newer frameworks. One of the things that turned me away from continued development before was the seeming lack of interest in such a project.
If I could get enough people interested in using it (and a couple of people to help develop it), I would definitely consider building a new and improved CMS that people could use.
If anyone is in fact interested in this, get ahold of me. With enough interest, I will start on it.
