I looked at the website and noticed that the landing and information pages for the communications journal are blank. The links out from the author information page to the rrik.org domain also don’t work (at least for me).
Regarding encouraging submissions, I think STORK members should really try to get the ball rolling. Outsiders/newcomers will be much less likely to submit to a journal that has not yet published anything. As for encouraging outside submissions, what about some kind of award for article of the year? A small journal in my field does this once per year for young researchers (i.e. the best article from a young investigator in a given year is awarded with a prize) and it seems to provide an upside for young researchers to submit there, even though the traditional metrics of the journal are not spectacular.
Another idea would be to solicit articles from people with interesting (perhaps open science-related) conference abstracts or blogs? This requires some work to source them though.
Just some ideas.
