We're happy to present this guide from WeddingChannel.com.
You're close with the bride and groom, so it's probably just fine if you simply text your RSVP, right? And you're so thrilled to be invited that you just can't wait to spread the word to everyone! Sound OK? Think again. Just because you're usually glued to Facebook and Twitter, doesn't mean you should use them to announce your friend's upcoming nuptials. In most circumstances, wedding etiquette is a little more old-fashioned. That means, mailing the RSVP card and containing your excitement solely to conversations with other wedding guests. Read on to find out our top 5 wedding guest digital faux pas — and make sure you don't commit these etiquette crimes yourself.
Don't give a wedding play-by-play.
"Just checked into John and Jane's wedding." "Bride walking down the aisle now." It may be hard to resist, but sharing minute-by-minute details about someone else's wedding on Facebook, Twitter or foursquare is not okay. Let the bride check-in to her own wedding if she wants. And when it comes to the engagement -- make sure you ask the bride whether the happy news is public yet — she might've only told a few friends so far and probably won't appreciate you sharing her engagement news on Facebook instead of her.
Don't be the paparazzi.
Just because you post what you eat every day on Flickr, doesn't mean the bride wants her bachelorette party, bridal shower and wedding seen by the world. According to a WeddingChannel.com poll, 40 percent of brides said posting photos online without permission or even a heads-up was their biggest digital wedding gripe. So ask before posting wedding-related photos and videos, and don't even think about posting unflattering wedding pictures and risque bachelorette party videos.
