Mike’s little gizmo works a treat. In fact I run one on both my 33s for the last year or more.
Cheers!  Andy

I think most people will have received their boards by now-- some may still arrive next week with our international friends a week or so after that.

Eventually I'll fill all that in and add even more pages. If there's anything anyone would like to contribute in the future-- from photos to videos to how-to articles or anything else-- I'd be glad to publish it credited to you. Heaven knows I'm a mere amateur compared to most of the people on this list, so I will only be able to share the few things I learn here and there or just link to other sites.
