Hi Andy,
Great question!
I don’t see why not = our plugins are nothing if not flexible – but it isn’t something that’s facilitated “out of the box”. Certainly if you were to take advantage of other features that come provided with WordPress itself, like user registration and profiles, you could roll what you have described into Community Events without too much work.
To summarize – it would need some customization work to achieve this, but nothing drastic 🙂
I hope that answers your questions but let me know if I can help with anything else.
