The site looks good. I don't know if these things were covered already, but I went through and made a list of things that I would change. I sent it to you on the "Feedback" form too.
Notes on Coordinator:
Home page after login: Text says "Sorry, you currently don't have any events listed."
No reason to be sorry. I would change to: "No events listed (or, You haven't planned anything yet!). Click here to add an event!" or something that provides a way to change the fact that there are not yet any events.
On creating an event: The date box doesn't have a default date shown. I can't see what today is. Maybe make the current day show up a different color or have days in the past grayed out.
On friends: Longer names get extended past the box representing friends, instead of wrapping or adjusting.
Contact Us link at the bottom of the page should bring me to a page with forms to fill out, not attempt to open outlook or whatever program I use for email. If I want to email you with these, provide your email address on the "Contact Us" page.
Last thing, the pages don't have a "What's next" button. Meaning, After I add friends, I'm brought back to the page to invite more friends. There's no "Thanks for adding friends. We'll let you know when they accept. Here's the button to go back to the home page."
