Like many other modern social networks, Friendica uses a special notation inside messages to indicate "tags" or contextual links to other entities.
|
|
|
|
**Mentions**
|
|
|
|
People are tagged by preceding their name with the @ character.
|
|
|
|
You can tag **persons who are in your social circle** by adding the "@"-sign in front of the name.
|
|
|
|
* @mike - indicates a known contact in your social circle whose nickname is "mike"
|
|
* @mike_macgirvin - indicates a known contact in your social circle whose full name is "Mike Macgirvin". Note that spaces cannot be used inside tags.
|
|
* @mike+151 - this form is used by the drop-down tag completion tool. It indicates the contact whose nickname is mike and whose contact identifier number is 151. The drop-down tool may be used to resolve people with duplicate nicknames.
|
|
|
|
You can tag a person on a different network or one that is **not in your social circle** by using the following notation:
|
|
|
|
* @mike@macgirvin.com - This is called a "remote mention" and can only be an email-style locator, not a web URL.
|
|
|
|
Unless their system blocks unsolicited "mentions", the person tagged will likely receive a "Mention" post/activity or become a direct participant in the conversation in the case of public posts.
|
|
Friendica blocks incoming “mentions” from people with no relationship to you.
|
|
The exception is an ongoing conversation started from a contact of both you and the 3rd person or a conversation in a forum where you are a member of.
|
|
This is a spam prevention measure.
|
|
|
|
Remote mentions are delivered using the OStatus protocol.
|
|
This protocol is used by Friendica and GNU Social and several other systems like Mastodon, but is not currently implemented in Diaspora.
|
|
As the OStatus protocol allows this Friendica user can be @-mentioned by users from platforms using this protocol in conversations if the "Enable OStatus support" is activated on the Friendica node.
|
|
These @-mentions wont be blocked, even if there is no relationship between the sender and the receiver of the message.
|
|
|
|
Friendica makes no distinction between people and forums for the purpose of tagging.
|
|
You can use @-mentions for forums like for other accounts to tag the forum.
|
|
If you want to post something exclusively to a forum (e.g. the support forum) please use the bang-notation instead of the @tag.
|
|
So !helpers will be an exclusive posting to the support forum if you are connected with the forum.
|
|
If you select a forum from the ACL a !-mention will be added automatically to your posting.
|
|
|
|
If you sort your contacts into groups, you cannot @-mention these groups.
|
|
But you can select the group in the access control when creating a new posting, to allow (or disallow) a certain group of people to see the posting.
|
|
See [Groups and Privacy](help/Groups-and-Privacy) for more details about grouping your contacts.
|
|
|
|
**Topical Tags**
|
|
|
|
Topical tags are indicated by preceding the tag name with the # character.
|
|
This will create a link in the post to a generalised site search for the term provided.
|
|
For example, #cars will provide a search link for all posts mentioning 'cars' on your site.
|
|
Topical tags are generally a minimum of three characters in length.
|
|
Shorter search terms are not likely to yield any search results, although this depends on the database configuration.
|
|
The same rules apply as with names that spaces within tags are represented by the underscore character.
|
|
It is therefore not possible to create a tag whose target contains an underscore.
|
|
|
|
Topical tags are also not linked if they are purely numeric, e.g. #1.
|
|
If you wish to use a numerica hashtag, please add some descriptive text such as #2012-elections.
