Research shows this is what I want! But a few questions first.
Which version of PHP should my host be running?
If I install on siteb dot com, can the return email address be from sitea dot com or must they be on the same domain?
Without payment, can I file tickets to keep track of user issues and issues in general?
I'd install on my domain via Windows but can I access the system via iPad? Seems obvious, I know, but another recommendation doesn't allow this. I am usually on iPad but switch to laptop when needed.
Thank you
