I have a publishing engine I have been developing for thirty months but find myself being unable to work on it during my masters degree. I would like to make it open source in the interim to get others to use it and improve how it works.

I would like to consider a licensing system that allows for multiple instances of the software for singular users (ie, a newspaper/magazine or zine hosting the code on their own).

I would like to limit it from becoming the basis of a larger magazine hosting service right now because it is intended to be an integral part of a much larger publishing ecosystem which allows for the creation, dissemination and collection of publications as a free or very inexpensive service.

Right now there is no license associated with it, which is why I am not posting a link here.

(This system was developed to counter implied censorship for digital magazines and remove costly and confusing 'barriers to entry' for creators wishing to make interactive digital content. It is intended to be useful for free, but I would like to prevent people taking the code and using it to take advantage of others. It needs a bit of work to separate the content from the page itself to allow the access of multiple which I cannot develop right now)

Any help or suggestion on how to handle licensing this code for contributions and use would be appreciated, and if anyone would like to see examples or the github I would be happy to send it.
