Currently we work hard on expanding our add-on database. In addition our ultimate goal is to make sure that all add-ons published on our website our tested and well documented.
OTRS is a great piece of software but only if community will wake up and start moving forward a little bit more actively then it's doing it now.
If you have created a piece of software on OTRS which you'd like to share it as a Premium or Free - drop us a line :)
