I already started with an Issue Tracker, connected to my userdatabase from my original website, where I want to use my issue tracker.
I noticed, it isn't that hard to add a new issue, comment or something else to the database.
Tomorrow, or this week, I'll try to make a system that's based on charts and things like that, and I'll integrate it in my live website, ...
I'll keep you guys posted.
Maybe I'll try to add the codes? If there is anyone out there who wants to share his current code, of a sort of web API, feel free to contact me, or to post here!
