即時訊息 (Instant Message, IM) 就是可讓兩位[[Resident|居民]]私下對話的交談視窗。

當您跟別人公開交談時有距離 20 公尺的[[Limits|限制]]，但即時訊息就沒有這種限制，即使交談對象在 Second Life [[grid|網格]]的另一頭也沒問題。不過，一則即時訊息的長度限制為 1023 位元，或 1023 個半形字。

When a Resident is offline, up to 25 instant messages will be stored and delivered at the next login. This limit includes [[inventory]] offers, [[group]] notices, group invitation and IMs. All messages above this group limit will be ''capped'' and not delivered.

However, there is an IM to Email feature, which sends offline messages directly to the mailbox connected to your account. To activate it, go to '''Edit''' > '''Preferences''' (or press {{KeyCombo|ctrl=*|P}}), go to the '''Communication''' tab and check the '''Send IM to Email''' checkbox. Press '''Apply''' and close the window with '''OK'''.

When an offline message is received via Email, this message can also be answered via Email again. These mails will be converted back to IM and sent to the right Resident. Note that the Email to IM feature expires after 5 days after the receival of the IM. Messages sent afterwards won't be received anymore. Also note that the length of properly delivered Email replies is limited to 1023 bytes/single-byte characters. Messages exceeding this limited will be truncated to fit the limit.

Note that, due to {{Jira|SVC-1144}}, replies to offline emails currently can't contain special unicode characters.

Also note that '''offline IMs are only retained for 31 days and discarded afterwards'''. For example, if someone sends you an Instant Message and the next time you login is 33 days later, you won't get it.


== Conferences ==

A conference is a private conversation with two or more Residents, who can communicate gridwide. It is similar to group chat, but more dynamic, since everyone on your friends list can be invited, as well as everyone where you got a [[calling card]] from. 

To start a conference by
* selecting several Residents in your friends list ({{Keypress|Ctrl|title=Control}}+LEFT CLICK) and press "IM/Call" button.
* dragging a Resident's calling card into an IM window.

Once conference is started you can invite new Residents by dragging their calling card in the conference window.
