In Second Life, notecards are a way to deliver detailed information that won't fit in a single IM (Instant Message). Notecards are often used as product manuals by merchants, but your inventory window's Notecards folder can also be used like an email box to send and receive long messages.
In My Inventory, simply right-click anywhere and select New Notecard, or click the + button at the bottom of the window and select New Notecard.
The New Note will pop up. Now, you should write something appropriate.
When you're done, click Save and close the notecard by clicking the X. To rename the notecard, right-click it in your inventory, select Rename, and type in a more personalized title.
Sending a notecard
Now that you've written your notecard, you may want to send it to someone. If that person's avatar is standing nearby, simply drag the notecard from your inventory to the avatar. Otherwise:
Right-click the notecard in your inventory and select Share. The CHOOSE RESIDENT window opens.
If the recipient is your friend, click his or her name under Select a person.
If the recipient is not on your Friends list, click the Search tab, type the name into the search field, and click Go. Click on the correct name in the list of search results.
A window opens asking if you are sure you want to share your note with the Resident you've selected. If you're sure, click Ok.
If the recipient is online, the notecard is received immediately. If not, it is stored to the person's inventory.
Receiving a notecard
Check for new notecards when you log in by opening the inventory window's Notecards folder. You can read any notecards inside by double-clicking on them.
Embedding items in a notecard
You can attach nearly any type of inventory item to a notecard. Attached images and landmarks can make a fabulous addition to informational notecards, and notecards-within-notecards can provide you with some interesting options for organizing your text.
To attach an inventory item to your notecard:
Open a notecard you own or create a new notecard.
Make sure the item you wish to attach is fully permissive. The next owner permissions must allow copy, modify, and transfer. For more information, see Permissions on objects.
Drag the item from the My Inventory window onto the Notecard window. You can drop in any kind of inventory item, excluding calling cards.
The item appears as a hyperlink in the notecard.
Tip: If Second Life does not allow you to drop the item into your notecard, make sure to check the permissions on the object. If applicable, also check the permissions on any inventory items contained inside the object. A notecard will only accept fully permissive attachments, so it is not a good idea to attach anything you do not want other people to copy.
How to stop notecard spam
In rare instances you may get spammed with notecards, so that notecard after notecard pops up on your screen. If this happens to you, select Block Owner from the dialogue box that offers you the notecard.
Notecard spam is often caused unintenionally by scripting errors. However, intentional notecard spam constitutes abuse and is considered "Disturbing the Peace" by Second Life's Community Standards. If you believe you are being spammed deliberately (for instance, because the content of the notecards is vulgar or threatening), please use Help > Report Abuse to send an abuse report. See Filing an abuse report for more information.
