For those who don't have an account with the RPF, members at the RPF usually have non-members that want to post, post via a friend who's a member of the same forum.
For example,
Smick, if you wanted to post on the RPF, but didn't have an account, you could send a PM to me (I'm a member of the RPF) and I'd post your info, and say, smick from the 405th forums asked me to post this on his behalf...etc...etc.
At least that's what I did when I wasn't a member, but then they opened up membership and I registered.
They did it for me in June I think...don't remember exactly..
If you'd like me to post stuff for you, I'd be completely willing to.
