I like that it is easy for new users because of its simple layout/interface as well if used properly (and not too much) it works perfectly fine! What isn't great about prowl? Honestly nothing major at this point unless someone else does something different.
Definitely give your team access before hand so they have an idea how things work prior - no sense wasting everyone's valuable resources when there are other options out their!! This saves us tons og paper and also helps make sure we're getting our stories done efficiently since anyone who could use these services needs some editing or writing skills anyway haha.
