After following posts for a number of years I have learned the Time-Nuts community are not only a good source of knowledge but more important a great group of people. But even knowing that I am a bit overwhelmed after personally meeting several Time Nuts.  Of coure this is common knowledge to may of you long time members. That said the chance to get to know Magnus, David, John, and locals Hank and Skip has left me thinking..... 
In my humble opinion it would be great to put together an annual gathering of the Time and Freq Community, perhaps in conjunction with NIST's annual Seminar. If the time I have spent with Magnus and the other visiting Time-Nuts is any indication I  think a Time-Nuts gathering would quickly develop into the must attend event for people serious about time but the fantastic people researching it. I see this evolving not only a social gathering, but also a place for professions and amateurs to could showcase ideas and products. 
Best Wishes;

Thomas Knox
