A test environment is always a good idea.
Somewhere to try things out before making changes to the actual membership site.
Think of the test environment as a safety net.
We all likely have a similar story or two. The classic tale about making an adjustment on a live site only to find out later that seemingly small change resulted in a bigger problem. Whenever we find ourselves in this situation, we often think… This wouldn’t have happened if I did some quick testing first.
So, a test site running WishList Member sounds like a logical solution.
The next question being, can a WishList Member license be used on a test site?
