I formally request that you stop calling Rey and Finn their full (potential and likely) names, for those that may not wish to hear spoilers for Episode VII. It's fairly inconsiderate.
It's hardly a spoiler considering it's only speculation. They haven't confirmed those character's last names as far as I know.
I was once told to tone down on spoilers when I wrote a paragraph on the grave robber concept when people still thought that was super-canon.
If it was a spoiler I would have had to seen the film or read the script. Could just as easily be "Rey Jade." "Rey Fett." Maybe even "Rey Wren." As to Finn, is he going to be "Finn Windu?" "Finn Calrissian?" "Finn Skywalker?"
