Not exactly a Great Plains specific event, but definitely something for Microsoft Developer's to check out:

TechDays is a free, one day (24 hour), live virtual conference/event. It's on the web, so its in your region! Sign up and build your schedule already. Don't worry, you don't have to attend the whole 24 hours (except you hard core devs, you know who you are). Did I mention that it's free?

Check out the new OFFICIAL blog of Dynamics Great Plains called Inside Microsoft Dynamics GP!

Since this is straight from the horse's mouth, this blog should be a great source of official information right from the guys at MS!
