The Prototype community now has its own group on LinkedIn.
It's a great opportunity to connect with other developers and designers who are using Prototype in their daily work, get to know them better, and put a face next to the names you see daily in the mailing lists or on IRC.
Joining is as easy as following this link (Note: LinkedIn asks that members be manually approved, I'll try to process your joining requests as fast as possible):
Don't forget to add your blog or personal website to your profile, it's a lot more fun.
Looking forward to see you there.
