Overall airSlate SignNow was a great tool for what we needed! Our students were able to fill out the document within their availability and we were able to receive them in a timely manner! We will continue to use airSlate SignNow for these types of issues in the future!

As a user of airSlate SignNow, it has helped our department immensely! We've had to make changes and have students sign-off on the changes made to their program of study outlines. This required us to create a document that all students would need to sign electronically but unfortunately all our students were on campus during different dates and times. This posed a problem to us but with airSlate SignNow we had our solution! We emailed the document to the students with an eSignature required field and was able to get all the documents back!
