A couple of weeks back we attended the 2015 Technology for Associations Congress at the Hilton London Metropole. This two-day conference was designed to provide insights and helpful advice on how to use technology-and how not to use it-to overcome some of the most challenging issues facing societies and associations today. Topics covered ranged from CRM integration to how to hashtag. There were four main themes: event technology, making the right decisions on technology, Data and CRM, and E-learning and each theme contained a mixture of presentations and panel discussions. It was great to hear case studies from societies and associations and get expert advice from partner organizations and consultants. Take a look at our highlights and key takeaways arising from the tweets around the conference #ACTech15. Thanks to the delegates and speakers whose excellent tweets we've shared below.
