I think we've been using the on-line application for about three years now. Our bigger challenge is we do not control the website, so everytime marketing makes a change we have to update our instructions on telling people how to find it.
I don't think we've seen a major difference between paper and on-line processing in terms of drop-outs. It's still about 50% of those who apply actually interview and 50% of those who interview actually begin service. So handling on-line apps is much easier than all that paper.
We do not do orientation on-line, so the application is just a convenient way to handle and track the on-boarding of a new volunteer. They do get an automatic follow up when submitted, but that message says to call us if further contact doesn't happen within two week's time. Unfortunately, they typically expect a speedy reponse, but first thing we do is check their references before they get a call for an interview, so they may not hear from us if a reference contact is unresponsive.
