For steemit chat, click on the 3 bars at the upper right corner of your page. There is a link near the bottom of the drop down menu. For the minnowsupport project you have to use discord. It is an app you download to your phone. On a standard computer in not sure. I'll see if i can find an invite link to get you in the group. I'm a little low-tech so it may take some searching :-)
