In one sentence, describe what the following article is about:

Odds are you’re going to want to remember this party and brag about it on Facebook, Twitter, and whatever other social media platforms you use, in addition to remembering it for years to come. So start taking pictures! Whether they’re of the table-full of macaroni n’ cheeses (at a mac n’ cheese tasting, of course), you and your friends all dressed up, or your sweet disco ball, it’s all good. In fact, take pictures of everything. If you're going all out, set up a "photo booth" – an area of the room set up specifically for taking photos. Place a piece of fabric on the backdrop, decorate it as you see fit, and keep a basket of props handy for people to use to take funny photos. It's also a good activity for bored guests. You probably have a whole bunch of people at your party that don’t know each other super well. In that case, you’ll have to be the link between them, bridging the gap. To make everyone feel a little bit more comfortable (especially toward the beginning), be a butterfly, flitting around from group to group, introducing everyone and diffusing the tension. When the fun really gets started, you’ll see people making new friends thanks to you. If this an issue, consider getting a game together that involves everyone. Charades, Heads Up, and even games like Truth or Dare can be classic hits. Parties get messy and they get messy fast. What’s more, people are notorious for not being polite and clean in a party environment, especially when it’s not in their house. Whether you’re in your house or at a public venue, it may be up to you to keep the area relatively neat and tidy. It doesn’t have to be spotless, but you definitely don’t want a tower of garbage accumulating on your drinks table, you know? Be sure to keep the trash and recycling in an open area. If it gets full, people will likely keep piling it up until its unmanageable, so get at it as soon as possible to avoid it spilling everywhere later in the night. The party’s at your house and there’s alcohol? Then your guests are your responsibility. Take their keys at the beginning of the party, hide them all in a bowl somewhere, and only give them back if they’re sober at the end of the night. You could also designate someone as the key keeper, so you’re not dealing with all the responsibilities. If you know someone isn’t drinking of their own accord, ask them if they could do this for you – you already have to deal with everything else! Whether it’s leftover food, a cupcake, or a party favor, it’s nice to have something for your guests to leave the party with – and it’s less clutter for you to worry about. That way everyone leaves with a piece of the party, feeling like they were involved and had a good time. Make sure to tag everyone in all your photos, too, when all is said and done. People will be reminded of how fun your party was and be looking forward to your next one. What will the next party's theme be?

Summary:
Take pictures. Be a social butterfly. Clean as you go. If your guests are drinking in your home, take their keys. As your guests leave, give them a token from the party.
