TSU is finally here

I got an email from TSU  informing me that they will reinstate my old account in a few days.  My problem is they want me to get their App either from the App Store or Google Play.  I am not sure they will let me participate without the App.  I have written to them and am  awaiting their response.  

I have forgotten what it is all about  There is a video that explains everything but unless I know it is OK for me to be there without the App I will not waste my time. 

I have a few friends there
