My point was that it's not environmentally desirable to produce magazines.

Seeing as you have a uniquely digitally inclined audience, a shortage of funds and a global market, PDFs do make a lot more sense.

I didn't mean to devalue any potential content.

Your costs are very high. There's no reason you need London overheads for an English magazine on technical content. For example, I know many first language, highly literate, technical English speakers who with extensive writing experience would be happy to edit such content at much cheaper rates than 100GBP per page. For example, 10 GBP per page. https://en.wikipedia.org/wiki/International_inequality
