If you like Telegram better than IRC, and you want to stay in touch during the Wikimania days, you could consider joining the unofficial Wikimania 2017 Social group on Telegram.
In this group, the code of conduct for Wikimedia technical spaces is in effect. No idea what that means? Better read it first: https://www.mediawiki.org/wiki/Code_of_Conduct
If you take issue with anything that happens in the channel, please contact a channel administrator.
Cheers!
