The biggest complaint I hear about open source in general is the lack of documentation. Writing good documentation is hard, and with complex tools like OpenNMS, sometimes a more hand-on, interactive approach is better.
That is why we periodically offer training. We have two courses scheduled for September.
The first is the week of 12-16 September and will be held at the OpenNMS HQ in Pittsboro, North Carolina.
The second is the week of 26-30 September and will be held in Fulda, Germany, the site of our Users Conference back in May. We are happy to be able to offer this in conjunction with our partner, NETHINKS.
Both courses will be taught by me and David Hustace, so if the thought of listening to me talk for hours on end frightens you, take solace in the fact that David teaches half of it.
Hope to see you there.
