With respect to the PSIA forum software, the most annoying aspect is the timeout when writing a long post. The editing capability of the current software is minimal. You can't see the text of the message you are replying to and it lacks the ability to highlight quotes, insert pictures and urls. Either the current PSIA forum software is either set up to automatically delete old posts or that's a feature of the software. Either way, this feature can be highly annoying when informative posts disappear.
At the time the PSIA software was chosen, the people making the decisions were not users of the forum. They made their choice based on criteria that were important to them. I'm sure purchase cost and maintenance costs were high on the list. Very nice forum software can now be had for low or no cost. PSIA has chosen not to actively moderate their forums. They will if someone complains about a specific post. Epic Ski has proven that having a volunteer from the active community act as a moderator can work. Having an active moderator is a key to a successfull online community. Since the people that make the decisions do not understand what online communities are about, they are unaware that the system would benefit greatly from an upgrade and can be upgraded at little or no cost.
PSIA could do a lot to improve their online forum. Unfortunately, the last "upgrade" only succeeded in driving the most active users to Epic Ski and beyond. Now it's a catch 22. The PSIA forum can not attract many users because the software stinks and there are so few people there. Since few people use the forum, there's no reason to improve it. If PSIA management would put the effort into learning about the value of an online community, they would realize that the time and effort required to regain the trust of the active users could provide returns many fold. Greater participation from the membership translates into greater knowledge transfer and the opportunity for more "applications" (e.g. a support resource for clinics).
It is telling that the PSIA Snowboard forum is 50% more active than the Alpine forum from a small fraction of the membership base. It's also telling that demo team members actively participate on the Snowboard forum, but not on the Alpine forum. If PSIA wants to improve their online community, the first thing they need to do is "get it" instead of treating it as a pain in the neck.
