Mashable and Regator are teaming up to organize the first ever Mashable event in Atlanta, where MailChimp also happens to be headquartered. (Shameless plug, but OK– we’re also one of the event’s sponsors.) Originally limited to 200 tickets, the mixer was slated to be held at the PASTE magazine offices in Decatur, Georgia. Demand was so overwhelming that Mashable and Regator decided to print an extra 100 tickets and move the event to a bigger space though.

The event is being held at The Trolley Barn in Inman Park (963 Edgewood Avenue), a restored 1800′s trolley depot, and some of the lovely MailChimpsters will be there. Please say hello to Co-Founders Dan and Ben, as well as Chief Twitter Officer Amanda if you are attending! We’ll have some sweet MailChimp tshirts to give away as door prizes, as well as NinjaChimp stickers and 1″ buttons. You can never really have enough monkey love now can you?

The special guests from Mashable include Editor-in-Chief Adam Ostrow, COO Adam Hirsch, Features Editor Sharon Feder, and East Coast Events Coordinator Bret Petersel. Also in attendance will be Regator’s three cofounders–Chris Turner, Kimberly Turner, and Scott Lockhart–as well as the best and brightest minds in the social media, tech, startup, blogging, media, and creative communities in Atlanta and across the Southeast. You definitely don’t want to miss this one!
