I may have said this before:
Can you look at switching the forum over to a PHP-based bulletin board such as IP board
www.invisionpower.com or similar?
This would allow for better searching, the ability to privately contact contributors, and email notifications of updates on threads (among other things).
There is an added cost, but it is not prohibitive ($400-800p.a. depending on license and whether you want continual upgrades) and this includes full support and upgrades. For $200 you can buy the basic license and opt out of the upgrade package which equals minimal on-going costs.
Not high costs based on the benefit, and the slick interface may encourage greater use of the forum.
Helpdesk staff could use the forum to answer general questions, and private message users with specific solutions. Helpdesk staff could direct users to the forum for help and free up call lines.
While on the topic, I would use a IM-based (Instant Messaging) help desk if one were set up. Once again there are inexpensive IM products on the market designed for help-desk solutions.
Just some ideas. Landonline is cutting-edge in many respects. The forum/help desk is not quite up to the same level of advancement.
That said, I applaud the help desk staff. The Landonline help desk is the most customer-friendly and knowledgeable I have ever dealt with. kudos.
