Collabtive's death has been greatly exaggerated
So it seems like Collabtive, the open source project management platform that I use and have promoted here in the past, is not nearly as dead as I thought it was!
It turns out I had found (and had been following) a different repository on GitHub and not an official one. The official GitHub repository seems to show that it was last updated within the last week.
This is great news and as soon as I get a chance I’ll be updating the version I’m running, I’ll also look at maybe getting involved in it’s development.
