I need to build an online journal managing system where people can start their own [personal/public] journals (like wordpress has blogs). Since it is a journal, the users should be able to assign editors, reviewers, etc.
I'm aware of Open Journal Systems but it doesn't allow anyone to launch their journal. Also, I've only a week of time.
Which platform would be best suited for such thing? I'm thinking PHP, but I'd love any other platform which can speed up the process.
What do you mean by Open Journal System not allowing anyone to launch their own journal? The software can be downloaded freely (http://pkp.sfu.ca/ojs_download) and run on a LAMP server just as Wordpress is. OJS has all of the necessary journal management requirements (editorial/reviewer roles, publication of documents for public consumption) built right in, and is extensible in many ways.
