A First Iteration for Events II

I've done more work to define what I think a reasonable "first pass" could look like for events. My objective is to establish end-to-end functionality, but to cut back on features so that this phase could be completed in a relatively short timeline. I have used the UCs from my original pass through and so this new diagram is a subset of the original:

So to be clear - I'm interested in using what is already available as well as coding up what isn't to achieve the above. Hopefully I'll start on this within the week. I've altered the UCs overall slightly - but nothing major. Also I'm using a new modeling tool - so we'll see how that goes.
