First of all click on the group you wish to post a message to.  Then to post a message or binary attachment either press “p” on your keyboard while 40tude has focus, or select “Post”->”New post to newsgroup” from the menu.  You will be presented with the following screen:

Enter a subject and the actual message itself.  If you wish to change your username or email before posting select the “All headers” tab.  To post one or more attachments select the “Attachments” tab, and then click “Add attachments”. 

Once you’ve finished composting the message select the  button to post the message or alternatively select “Action”->”Send now” from the toolbar menu at the top.

If you’ve tried posting an attachment, you’ll notice that you have the choice of three encoding methods, namely Mime (Base64), UUencoding or yEnc.  When adding multiple files (attachments) 40tude will automatically select Mime (Base64) as the default encoding method.  Although you can change this by highlighting a file, then selecting “Encoding” and choosing a setting from the drop down menu, only one file can be changed at a time.  This would obviously time very time consuming if you wished to post say 40 attachments with yEnc encoding.

Therefore, if you wish to change the default encoding method, go back to the main 40tude Dialog Window, and select “Settings”-> “General Settings”->”Attachments”.  Near the bottom you will the settings below:

Select the required option and then click ok to exit “General Settings”.
