Non profit org (NPO) is holding a conference with speakers. The conference is free to the first 100 people who sign up. Signing up consists of typing your first name, last name e-mail and company affiliation into a form somewhere. The office manager will need to be able to track the attendance and perhaps print off name tags.
What is a free on-line tool that will allow NPO to manage this without me having to charge them to build a custom web-app?
