CHASE is an annual conference/exhibition for charities and associations... http://www.conferencehouse.co.uk/CHASE/chase_home.aspx ...organised in London and has been running for some years now.
I was invited to participate in a round-table discussion on CRM based on SaaS (ie 'cloud computing') technology to represent CiviCRM at this event, and I thought it would be good to establish an exhibition stand to represent CiviCRM at this event. I invited other London-based CiviCRM service providers to collaborate on this event and five of us agreed to share the costs of the stand -
I should also acknowledge that CiviCRM user Seamless Relocation sponsored our stand by lending us the display boards and the furniture that we used, eg the tables and chairs.
Although the stand was only 6 sq m (3m wide x 2m deep) I have to say that we were fortunate to get a stand in a prominent position, but I don't know how much this helped in attracting the impressive number of visitors that we had during the two days of the event.
