Hey Merlin. Kudos on your success with 43 Folders. Consider this a shout-out from Tallahassee. I would highly recommend the SpamBayes plugin for Outlook. It's the original free open-source python-based bayesean spam filter that most other Baysean filters have evolved from in one way or another. It was based on the work of Paul Graham who was one of the first people to apply Baysean techniques to catching spam. If properly trained on good and bad email you can easily tame your inbox. Personally, it cleans out over 400 spam messages per day from my inbox and I don't think I've ever had a false positive. The nice thing about this filter that I have not seen in other spam filters is the "unsure" folder where email that can't be classified as either spam or non-spam ends up. This way you only have to look through a handful of spam messages each day to ensure you aren't getting any false positives. Spambully is another highly rated commercial filter that does this, and (surprise) it is based on the original SpamBayes filter. I've never heard of Adrian Trenholm's filter so I can't comment on that one.

Also, I would have to say Google Desktop has become one of my favorite general use tools. I use it to find Outlook messages and anything else I lose on my PC. I use the integrated scratch pad and todo list widgets constantly and there's plenty of other (mostly useless) widgets available for those with extra desktop space to burn. If I ever switch to Gmail, I'll probably use their calendar widget too.
