I am not sure whether or not this has been considered or not yet, but recently I have been using discord instead of TS with many of my friends and I have been having a generally favorable time with it. First off I feel it has a better and more efficient design than TS currently has. Another thing to mention is that it completely free. The application for Windows/Android/iOS/Browser is completely free, and creating a server is also free. A server can be shared using a web link rather than an address. I have just found this to be a very nice alternative to TS, and in my opinion in actually better. I figured it could save a few bucks too. Here is a link to the program: https://discordapp.com/ If you have not seen discord yet I certainly recommend taking a peak!
