The Outbox and Outbox Toolbar

    

  Outbox Toolbar Button
When you "Send" - Gravity places the outgoing article/message into the  Outbox.  A background thread checks for new articles in the Outbox periodically and it sends them automatically to the news or e-mail server.

The Outbox Toolbar

The Outbox Toolbar also accesses the Outbox. It shows how many articles are queued for sending and posting errors, if any. The Outbox bar can be dragged to another location by holding down the left mouse button.
If you do not see the Outbox bar, enable it with View - Toolbars - Outbox Bar.

The Gravity Outbox  
  You see a check mark and time stamp for sent items. 
  The item has not been sent.
  A red X means there was an error posting (you can try to resend it)

If you double-click a message, you can see the article contents in the bottom window.

Back to Draft
You can revise the contents of an Outbox message by selecting the article, then clicking the Back to Draft button. This sends the message to . To edit the message, you must open it from the View - Other windows - Draft Messages window.
Retry Send
If a message failed to post, you can select the item and use the Retry Send button. Gravity will make another post attempt during the next posting cycle.
Delete
Select the item and click the Delete button to remove an item from the Outbox. If you have sent an item you delete, you remove it from the database. Otherwise, sending is cancelled.
Cancel Article
If you have posted an article to a news server, you can cancel the post by selecting the article and clicking the Cancel Article button.
Depending on how quickly you do this after it has been transmitted to the news server, no one or only the users of the news server may see it.  If you do it too late, then the article may have been propagated to other news servers on the Internet. Not all servers honor cancel requests.

On Shutdown, remove sent items after ... days
You can purge Outbox messages automatically by enabling "On shutdown, remove sent items after xx days." This prevents your Outbox from taking up too much disk space and also speeds up the Outbox loading.
