The Tag system allows you to mass-select either mail messages, old mail messages or news articles which you can then perform functions on them, as a whole. For example you may wish to tag an interesting news thread as well as a collection of e-mails you have received regarding the thread and save them as a plain text file to import into Microsoft Word.
Tag a message: The process of tagging is identical to that of marking mail or news items as read or unread, simply highlight the item or multi-select the items you wish to tag and press 'T'. The tag box (shown below) has been replaced in 2.20 by a drop down menu that appears at the top of the screen when one or more items have been tagged.
Resets the auto expiry flag for all tagged items.
