If you're looking for conferences to submit abstracts on anything web, cloud, mobile, or even soft skill related, this is an amazing Midwest-regional multi-day conference. It's held at an excellent location (the Kalahari in Wisconsin Dells), and the entire family is invited!
Hope to see you (speaking) there! For more information, visit the THAT Conference website.
