New Runtime(s)
in New Users
I'm completely starting over.
So I'll have Gen1, 2, 3 and Poser.
Is there a reason(s) I just don't want to make 1 oganized (organised for Dson portion & Poser) Runtime with everything in it?
Thank you

The main reason I see to use multiple Runtimes is to separate the content you have into smaller libraries, so you can choose to load only some of them if you don't need the others.
That can be pretty useful when you have tons of content ;)
It can also be useful to separate non-commercial freebies from the rest of your content if you make commercial work.
If content is already installed then yes, I would uninstall and reinstall.
Unless something has changed more recently, the advice that has always been given by the DAZ folks is not to create too many content libraries. Although the CMS database can handle more than one, I suspect that the problem lies in the resource overhead involved in having the database keep track of multiple repositories, but I am simply guessing at that.
Support recommended using only one to me.
You people were my 2nd opinion(s). :)
