Well, obviously the fact that it is an unpaid position is less than ideal, but that aside I only have a few suggestions. There is a GlobalGiving language and there isn't really a great dictionary. Being an online org, there are many tools for metrics, volume, organizing, and just general operations. You are pretty thrust into it all with the expectation that you pick up the jargon along the way. It is very difficult to try and have a conversation about something very specific that has an even more specific name. I felt it sometimes limited my ability to act quickly and know the best way to do something.
