Sorry, this doesn't work for me. If the problem is with the printers, change the printers. If it's a money problem, fair enough - all publications run into them from time to time, but 6 months between issues? That really is taking the biscuit.
Come clean John.
Even during the Tau Press days when Steve was writing a fair chunk of the mag it was never this bad. If you can't handle it, either let the mag die or sell it on or make it an online, wiki based system. Folks have fond memories of AU (including me!) and what has happened since it was sold is bloomin' awful.
I'm not taking sides on this as from my experience, putting together a magazine is not an easy thing to do. However, you owe it to your readers and subscribers to explain fully and frankly what the problem is. Don't hide and duck lest you end up like a certain Saltly based RISC OS company...
