Thanks for the comments brandorr. We took a look at wiki's when planning the rollout of this site and decided that a forum approach would best suit our users. I'm interested in your feelings as to how a wiki could benefit this community and if, in your mind, it would be a replacement for the forums or something you would use in parallel with them.
The key for us would be that it fits into our portal framework (authentication/etc) and from first glance it looks like twiki wouldn't be a "simple fit".
Again, thanks for your feedback and I look forward to hearing more about how you would use a wiki and what exactly is stopping you from using the forums to pass along your knowledge. Also, if you could state why specifically you feel they are "unorganized", we might be able to "organize" them a bit better in the meantime...
