I've attended a couple of Webinars and tried to attend a couple more. The most useful one I've attended was training on EVanced (our summer reading program software). I appreciate that the SRP webinars exist and are easy to understand, in part cause they taught me and it meant I didn't have to create new training for my staff.
There are a couple of Webinars from Nebraska that I will definitely be checking out. I've already suggested a Webinar from the list to one of my staff members. I think there's a lot of my staff that would be interested in Webinars specific to children's services. As budgets are being slashed and local professional development opportunities (or the chance to go to one) are dwindling Webinars can be a great tool.
