Sue, I just canceled my RSVP. While I'd really like to attend, I don't think I'm quite ready to for this event. I'll target the next one. Thanks!

Figured out how to do location-based searching on Twitter. I can't find an app that supports it (but there may be), but it works on the Twitter web site.

If I enter: pain near:seattle

It will give me all references to pain in the vicinity of Seattle.

Thanks to this link for explaining advanced Twitter searching to me: http://www.searchenginejournal.com/how-to-search-twitter-the-advanced-guide/8034/
