So I'm a bit of a novice when it comes to PHP, but recently after lots of thought and weighing up the pro's and con's (and there is a lot to weigh up), I have decided to commit to using Dokuwiki as a knowledge store for the team in which I work.
Grand ideas almost always come with some degree of pain. This I can confirm, after searching for an open source issue tracker appropriate for my needs (and my colleagues), as well as one that either had a Wiki or would integrate well with one.
After looking at Trac, Flyspray and Mantis, I finally spent some time with Eventum which seemed to tick all the boxes.
After many years of plundering the vast resources of the open source community, it is with great pleasure that I can today put something back. See dokuwiki_eventum for my efforts (over several late nights) in integrating Dokuwiki and Eventum. Although it will be of benefit to us, I hope it is of use to someone else too.
