This is going to sound elitist/veteran-ist, but I highly recommend that both of you first get a good deal of roleplaying experience first. It is a very common tale of new people coming on and deciding they want to do some epic, long RP only for their idea to die out quickly because of one reason or another. And than said persons tend to just leave the site feeling that there is something wrong with the people on it because no one posts or is interactive enough.

I'm not trying to be condescending, but its a cautionary tale that happens a lot.
