I like that it is easy enough so people can use without needing an IT support person, but still has all of its functionality when you need someone who knows how to navigate your system better than yourself! The only thing i dislike right now are some bugs in our platform which have been resolved since we started using this software - however there was no warning or any indication before hand as far as what could happen if these were not fixed quickly (we did get them addressed though).
We're solving two problems at once here; 1) engagement 2) transparency into giving/receiving donations from supporters2.).
