Maybe I'm coming off in the wrong way. I was informed that maybe my hosting company had not opened the port necessary for me to be able to use RMS. I asked, then what port would they need opened.
There are quite a few ports .....
Now, I'm showing my ignorance to RMS and how it works.
What I need to know, I believe, is what port is needed for this to correctly work?
Plus, if all you need is to have your domain listed on a RMS host list, for you to work with that host. Why not charge users a nominal fee. Less then hosting, on account your using less resources, and create a shared RMS fee for around a buck $1.00 (USD) a month. This would be fair, and would be a win win situation for all concerned.
This way, there won't be as much traffic hitting one server.
Just a idea.
