How do I create new content without logging in?

If your community supports it, you can post new content simply by sending an email to the community. This can be especially handy for posting when you can't reach the community using a browser. For example, you could email content from a cell phone that sends email.

Each place in your community -- from spaces to projects to groups, for example -- provides email addresses for the content you can post via email. By sending email to the address corresponding to documents in the place, for example, you can create a document there. The subject line of your email will be the document's title, while the email's body will be its content body. Even your user profile provides email addresses for content you can post. For example, you can change your community status message.

To create content with email:

Go in your community to a place where you want to create content.
Under Actions, click Create by email.
In the Create By Email dialog box, select the check box for the content you want to create.
Click the Download vCards button.
When you're prompted, save the vCard (.vcf file) to your computer.
After you've saved the vCard, click Done.
In your email or address book program, use the vCard you downloaded to add its email address as a contact. For example, in Microsoft Outlook you can drag the vCard to your Contacts folder. On a Macintosh, you can double-click the vCard to add it to your address book.
In your email application, start a new message you'll send to the address you just added.
In the email's subject, type the title you want your content to have.
In the body of the email, type the main part of the content.
Send the email to create the content.
