It was easy enough that I could pick it up in about an hour or so without any help from my employer's IT department (which helped!). There are some minor quirks that keep me away from using it all day every working day but nothing serious - like having to manually create reports when you don't want them created automatically at certain times during the month etc. If someone has little experience then this program might be too complex though maybe less experienced users will have no problems learning its features quickly. We managed our donor database via Excel before we started using Aristotelis software which meant data entry errors were rife as people would make changes directly into their own personal spreadsheet rather than update the correct file first. Now our files are far cleaner because there aren't mistakes being made anymore.
