When composing a new message, a separate text message has to be added everytime.
I always use the same message telling the receiver to follow a link to the
online article

it would be usefull if there would be a standard message that you only have to
put in once maybe even as a text message template, similar in use as the current
(HTML) Message Template

also a smart variable like {$thisarticle} containing the direct link to the
article would be very usefull in both the text message and html message template
