Please please please use the lj-cut tag when you're posting spoilers (see below for definition) and label them as such
The lj-cut tag will be necessary to hide spoilers for the following 7 days after the episode aired. For instance, Loss aired October 14th, so any spoilers for that episode would require the lj-cut tag until October 21 - one week later (please see lawandordersvu's definition of spoiler below)
Please to also use the lj-cut tag when posting more than one picture at a time or a long article(I'll let you be the judge of what's too long)
Please don't be nasty to other people. We're all nice people here, so don't be an ass
Lastly, please go back and read previous entries if you have a specific question to see if it's been answered already (chances are good that it has).
Other than that, Play nice and have fun!
SPOILERS: Considered any information giving away major plot points of future episodes.
A NOTE: I'm going to say any information from NBC's website (ie: the episode synopses below) will not be considered a spoiler, however, any pictures from upcoming episodes will. Any episode is fair game and spoiler-free the following Tuesday(7 days) after it originally airs, which means no lj-cut will be necessary.
