There is the Bitshares Dex channel on Telegram, and this one too: If you want friendly wallet and password help, this is the place: https://web.telegram.org/#/im?p=@btsWalletHelp

Also, there is https://bitsharestalk.org/index.php where you can ask questions, make suggestions, go over the histyory, etc.

Also, a little digging around will help you find a developers channel, a marketers channel, and a discord bitshares channel.
