Preparing for EAGxPrague

I signed up for EAGxPrague somewhat last minute and am wondering what the best channel to ask questions and connect with fellow attendees is. This is my first EA conference and post on this form, so please go easy on me if I’m missing the obvious.

The post How to Make Your First EAG a Success recommends scheduling 1:1′s and mentions an app. Is this applicable to EAGxPrague? I’ve not seen any mention of an app for this conference.

One thing I’m wondering about is at what time the conference starts. As far as I can tell the web pages and emails only mention the days. This seems like a good question for some chat channel. Is there a chat, or other communication channel, dedicated to this conference?
