I understand and am thinking of doing the same. Which would mean shutting all my dearest Trek Sites down for a few weeks or simply getting mails in web and go away a once.
I made it through nearly two years (or longer) of spoilering and eagerly waiting and it was fantastic. I couldn't bear it, if some over-enthusiastic comes now or in a few days
"Hey, I've seen it yet and did you already know that Spock ..."
... just another month. Stef* can do that. In one month exactly I'm sitting in the cinema - unspoilered.
Have good luck gornski in avoiding the spoilers and a good ride, when watchig the movie.
.... will also dimm her Trek/web consume striktly down ...
