Hey Rick,
Indeed, support in general is a key driver of business nowadays. We also put a lot of focus on it. If you decide to use our plugins, and by chance you will need customer support, I do hope we will be able to show you none less than excellent support. 🙂
I checked that site and it looks like they are not using Community Events, nor Event Tickets.
They have a custom developed event category filter dropdown at the top.
Let me know if you need any more info.
Cheers,
Andras
