The new journal Discrete Analysis has just been launched.
Points to note.
1. It is an arXiv overlay journal. That means that to submit a paper you just post it to the arXiv and tell us that that is what you have done. If we accept it, we suggest revisions, you post those, and that's it. That enables us to keep our costs about two orders of magnitude lower than those of a traditional journal. Papers are free to read (obviously) and we make no charge to authors.
2. Contrary to what one might expect, the website of the journal adds considerable value to the articles, by presenting them properly. Thanks to the work of Scholastica, the platform we chose for the journal, the site looks beautiful and is laid out extremely thoughtfully (this will become clearer when we have more articles). We have also provided "Editorial introductions" for each article, which aim to place it in context and help you judge whether you might be interested in reading it. If you open one of these, it does not take you to a different page, but opens up in a box on the existing page. (In general, we have tried to minimize the amount of loading you have to do.)
I have written more about it in a blog post: https://gowers.wordpress.com/2016/03/01/discrete-analysis-launched/
