Does Positech have its own STEAM Group? If not, can you create one Cliffski? 
I’m not a regular on steam, so don’t know much about how that works? what is involved?
I think in order to create a steam group one would have to have a steam account (which is free to create), and from there you can create steam groups either via the Steam application (which needs to be downloaded), or from the steam community site steamcommunity.com/ . I don’t know if that made any sense
