I used to work on a quarterly published magazine (3 of us in our spare time). We took articles from members of our group and put them together for our society's magazine,
We put all the articles together in a Desktop Publishing software (we used Serifs "PagePlus") and created a PDF we uploaded to the printers.
Serif software no longer exists - This is replacement -
Affinity PublisherWe did look at publishing as an e-magazine - but club members preferred a paper based copy.
The publishers we used are in Warwick -
Warwick PrintFeel free to PM me if you want a chat about this.
