You'll also see a link to the **Global Directory**.
If you click through to the global directory, you will be presented with a list of everybody who chose to be listed across all instances of Friendica.
You will also see a "Show Community Forums" link, which will direct you to Groups, Forums and Fanpages.
You connect to people, groups and forums in the same way, except groups and forums will automatically accept your introduction request, whereas a human will approve you manually.
When you've submitted the connection page, it will take you back to your own site where you must then login (if necessary) and verify the connection request on *your* site.
Once you've done this, the two websites can communicate with each other to complete the process (after your new friend has approved the request).
If you know (for instance) "bob" on gnusocial.de (a GNU Social site) you could put bob@gnusocial.de into your Contact page and become friends across networks.
(Or you can put in the URL to Bob's gnusocial.de page if you wish).
If you have supplied your mailbox connection information on your Settings page, you can enter the email address of anybody that has sent you a message recently and have their email messages show up in your social stream.
If a friend of yours has an GNU Social account, they can become friends with you by putting your Friendica Identity Address into their GNU Social subscription dialog box.
Once you have become friends, if you find the person constantly sends you spam or worthless information, you can "Ignore" them - without breaking off the friendship or even alerting them to the fact that you aren't interested in anything they are saying.
In many ways they are like a "fan" - but they don't know this.
