"The IssueTrackerProduct"n:http://www.IssueTrackerProduct.com is my proud open source project that actually has become quite popular. My survey has received more than 150 reviews; some with comments like "Yours is by far the best thing i've seen".
I was starting to loose interest in it but the motivation is back again. People appreciate it and there are several new web development areas I have yet to discover and do more research in. For several months I've been thinking about a way to integrate a Knowledge Base into it and finally I think I have come up with a solution. It's all in my head so far but getting it there is a much bigger challenge than actually coding it.
Now I've written a little Future Plan that I intend to work by and keep updating. The pace will be sporadically slow until summer since I need to focus hard enough on my last university year, but I will not give up and there is also the plan of trying to make money on this through my company. (Don't worry, it'll still be Open Source, but we might charge for customisation, corporate features or ASP)
