Being able for me, my colleagues or our clients is very easy since I can upload files from anywhere using any device that has an internet connection (smartphone/tablet). The interface could be more user-friendly if they would add some features like tagging of articles which are useful when browsing through large amounts at one time without having all this data in your head anymore. Also it should have been possible easier than uploading via email address because sometimes you just want something faster but still getting everything right! This helps us during meetings where we usually do presentations by sending documents over emails so people don't feel left out even though everyone else gets these attachments too.
