What is a one-sentence summary of the following article?
Type up a quick post for the benefit of your more casual acquaintances. Show off a few choice photos of the two of you, along with any relevant details you want your followers to have about the wedding, bridal shower or other upcoming events. At this point, your engagement will have become common knowledge. Only share as much information as you're comfortable with on forums like Facebook. You have a right to your privacy, even on the internet. Share your announcement on multiple platforms (Facebook, Twitter, Instagram, etc.). That way, you can make sure it's seen by the greatest number of eyes. Many couples have even begun using hashtags to keep their posts cataloged across different apps and sites.  Try coming up with your own unique hashtag by making a play on the groom's name, such as “#TilHeathDoUsPart” or “#StarCrossedGlovers.” When your followers click on your hashtag, they'll be able to see all of your various posts in one place. Though it shouldn't be your go-to choice, email can be very useful for targeting many different people with the same message. It may be just the format you need to drop a line to an old coworker or beloved college professor. Be sure to blind copy your recipients so it won't appear like they're just another name on the list.  Just because email is quick doesn't mean you should rush it. Take the time to author a thorough, well-written message, and go over it to check for spelling and grammatical errors. You could even go the extra mile and personalize part of each message by bring up an old memory or asking questions specific to the person. When it comes to communicating with loved ones who are many miles away, programs like Skype and FaceTime can often be the next best thing to being in the same room. Since you and the other person are on camera, you'll be able to show off your ring and witness the delighted look on their face when you tell them you've found someone to spend your life with.  A live video chat can make it possible for you to address a whole crowd at once. Consider requesting a video chat if you live abroad, tend to travel a lot for work or find phone conversations to be too detached.

Summary:
Post about it on social media. Organize your wedding-related posts. Send an email. Set up a video chat.
