This may be a stupid question, and it may have been asked a ton of times, but I haven't been able to find an answer searching this site or google, so I am forced to post and look like a jerk.

Basically, when all is said and done, I am going to have one parent portal and multiple child portals. I want the user to have a single regstraion and user account that spans all of those portals (They log in with the same L/P on each portal). I have no problems digging into code and trying to mess with all of that to try and make it work, but I was wondering if there was an easier way to get it done. Is there some configuration setting that I need to flip, or something I need to do or set?

This seems like it should be a common idea, but I haven't been able to come up with anything resembling a viable solution, aside from me hacking away at the code.

Thanks in advance
