OK, I can see the value in that, and certainly in your case with so many different issues every year, it makes total sense.

If you are slow, like me (!), it takes a little while to recognise this! ;-)
I have to use one form for every single issue because I want the numbering for the articles in each issue to start from zero. The autonumbering field (laufnummer) is never reset.
I first tried placing the form into a separate file and including it with the include plugin in the page for each issue. This will not work as the autonumbering field will not budge. It has to occur in the topmost page that is displayed.
Well, yes, I did not say how many trials it took me to get this right. A certain amount of stubborness might be helpful. Also, it's only software and it's a wiki, and it will not break apart, particularly if you use a separate wiki for testing. Farming is your friend.
