Finding someone on another network
Searching for the members of your posse individually using the Find on Twitter feature is an easy way to get going, but it can be time-consuming and frustrating if you keep coming up empty. An often better way to go is to get Twitter to do some of the legwork for you.
Specifically, you can tell Twitter to rummage through your list of contacts on your Gmail, Yahoo!, AOL, Hotmail, or MSN account. If Twitter finds one or more tweeters, it displays them in a list.
Follow these steps to give this a whirl:
1. Sign in to your Twitter account.
2. Click Find People. The Find People page appears.
3. Click the Find on other networks tab.
4. Click the network you want to scour: Gmail, Yahoo, AOL, Hotmail, or MSN.
5. Type the e-mail address and password for that account.
6. Click Continue. Twitter connects to your account, downloads your contacts list, and then checks for matches in the Twitter database. If it finds any, it displays them in a list and selects the check box beside each person by default.
7. If there are any people you don’t want to follow, deselect the check box beside each of those people.
8. Click Follow. Twitter displays the Why not invite some friends? page, which lists all your contacts who don’t have a Twitter account. You can use this list to extend invitations to one or more contacts to join Twitter.
9. Select the check box beside each person you want to invite.
10. Click Invite. Twitter fires off an e-mail message to each person.
