A bit off topic perhaps, I did not know where to put it, but with your experience in university editorials pruning may help.
Are you aware of any CMS for non-academic electronic journals? That may take several as OJS. Non-academic but university journals could be news university magazines, poetry magazines, ..., which are usually updated daily or weekly. As university press we also carry this type of magazines, university content, and seek a solution for the electronic edition of all these magazines like OJS all academic journals.
Joomla! and Drupal seem very good CMS for this, and in fact I looked around at other universities and the majority use one of two CMS, but I do not know if the option to support multi-sites, able to manage multiple magazines with a single installation, that each publisher can give you an account of "manager" of its magazine, and that the base url is something like http://journalsnonacademics.web.es
and with each journal http://journalsnonacademics.web.es/rjou ... academic11
, with their own authors, editors, styles, structures, as we have with our OJS portal.
I heard it might be possible with Liferay, but I'm not sure.
