Shane,
Make no mistake, as echoed by the others, I think you are doing a great job, not just with the contests but overall in acting as a liaison between us as users and Festool.
I think a reason more people don't participate is that they are reluctant to put their work on display because they either don't think it is good enough or they don't want to subject themselves to the criticism that sometimes arises from other members. Such as why did you use maple, I would have used oak or why did you use that molding, I would have used this molding.
Another reason may be, as David Baker stated, that the odds of winning are small, so why bother.
As stated in a previous post, some products have been reviewed so many times, as a user I feel that anything I say has already been said.
Also as stated in previous posts, many of the contests have been restricted to a region, a product, or membership status.
