Jafo, thank you for suggesting other mods which work well with your own. That really helps us to maximize the amount of quality we can realize from your products.
I noticed in your post that you are interested in donations, which will motivate you to work more on plugins.
When I was at the akismet site, I noticed their system for gathering donations. Pure brilliance. I recommend setting up a page for yourself with a similar system. It would reap results. I was so impressed that I actually made a youtube video to share with other web masters in my clique.
