It would be great if you install Mumble - you can join the server and we can check if your internet connection is strong enough for you to receive and transmit to us. Check out @peppernrino's post for steps to join the Mumble server: https://steemit.com/gridcoin/@peppernrino/gridcoin-community-hangout-043-repost

As @jringo has indicated, we have community members who just listen and type so if you have problems with upload quality then you can still join and won't be alone in the chat box! :-)
