The vCampus community has been created as a communication platform betwwen OSIsoft, Partners and Customers.
The OSIsoft developers participate here and the vCampus team involves the OSIsoft developers on a case by case base. In fact, all of OSIsoft does take part on the vCampus community.
Some of your fellow vCampus All Stars - Chris Manhard and Mike Zboray - are OSIsoft developers for PI AF and Abacus, respectively.
In general, I would say that others are most likely to participate on topics for their respective products, especially around key milestone stages (e.g., CTP, Beta, etc.) of the upcoming version. For example, I have been monitoring certain forums more closely ever since CTP1 of the PI Data Archive back in mid-May.
Do you have any particularly pressing topics on your mind?
