People use Twitter for all sorts of reasons -- to find out what’s happening in the world right now, to share information and to connect with other users. To get started, go to Twitter.com and sign up for a free account. Do so by entering your name, email address, and desired password in the provided space. On the Twitter homepage, type your update into the Tweet box just below your name. You can also click the Tweet button to start a new tweet from any page. Every tweet has an author, an avatar, a username (preceded by the @ symbol) and a maximum of 240 characters of text. Don't worry, Twitter will count the characters for you. If you go over the limit, try using abbreviations or rephrasing some of your sentences. Click the Tweet button when you're ready to post. Your tweet appears immediately in the Timeline. If you want to pass along a tweet that you liked to your followers, click "Retweet." You can also type in your message and put “RT” and the person’s username before the entire string. For example, RT @username (the original tweet here). You will see the tweets from the people you follow and vice versa.
How to use the #AAAAIWAO18 hashtag
Hashtags are one of the most important and efficient ways of organizing information on Twitter. A hashtag is simply a way for people to search for tweets that have a common topic. Anyone can make a hashtag at any time, simply by typing a phrase of the form “#topic” in a tweet. To use the #AAAAIWAO18 hashtag, type your tweet, including #AAAAIWAO18 within the body of the tweet. Clicking on the hashtag in the Tweet allows you to see all the tweets using that hashtag. This is a way to organize your tweets from the annual meeting and other topics of interest to the AAAAI.
