What was the best part about using CIC iSign?
First of all, I have to say that this company is currently down, as they are making a change in the form of their own name. CIC and iSign should represent two different companies (just like what Upwork did to Elance, for example). Regardless. CIC was quite a reliable platform that didn't have much to offer like most other, competing companies do, but back in the day, I liked them. Nowadays, I look forward to finding better alternatives, honestly.
What would you change about your experience with CIC iSign?
Until something new arises from this company (whether you're thinking of CIC or iSign), I strongly suggest looking for better performing companies that actually work. This one does not. All they have now is a set-up notifier that is set to send you an email once the new company's website is up and running. Until then, they're pretty useless in the digital signature department.
Overall, I have to say that this company should be avoided FOR NOW, as they're completely useless to anyone at the moment. The day I posted this was March 19th 2016, and they have yet to come online and begin working and offering services. Anyways, my point is - when this new company emerges, make sure you ignore this review of mine.
