If all you want to know is how many people are in a particular UFT project:
Open any UFT project. Click File, and slide down to Project Information.
The 4th line down from the top of the window, just under Project Title, just above the top of the white box (description), it says:
Individuals. And there is a number after.
Now you know exactly how many people there are in that Project.
I also recommend buying TMG (there is small discount still available) and exploring TMG. When you think you are ready, 'GenBridge' your Data Set into TMG.
Doing this will not change a single thing in your UFT Project.
Explore your imported UFT Project that youcopied into TMG. Do not begin adding data into the TMG Data Set until you are reasonably comfortable with the program. In any event, don't destroy the UFT Project (or delete the UFT program) until you are really really sure you prefer TMG.
I started this explore and learn process last September. I began adding new data to a TMG project in April. (I am very conservative.) I am very glad I made the change. I did NOT lose any data GenBridging into TMG. The options you select when doing a GenBridge make a difference, so try out various combinations while you are exploring TMG.
I still have UFT program and Projects on my computer but that is only because I am planning to 'GenBridge' one project at a time. Maybe I will be ready to wipe UFT off my computer in a year of two.
