Are there any (online) communities for independent researchers? Perhaps a bit of background on myself is useful in this case. I've obtained a bachelor's and master's degree in pure mathematics and applied mathematics, respectively. Although I would like to do a PhD on a topic that is somewhat related to these fields, I suspect I will not be able to obtain a position due to my GPA (7.0 out of 10) and limited amount of contacts in academia (I've graduated almost two years ago). 

Despite of the limited perspectives for an academic career, I still have loads of ideas for research, and I'm eager to publish articles as an independent researcher in my spare time. More often than not, however, the research ideas only partially pertain to my area of expertise. Usually, I would like to apply some statistical methods to do research in some social science. For instance, I'd like to do a statistical comparison on the holocaust victims of different countries, or on the methods through which the media can influence governments. 

While I may be quite good at formulating research questions and doing statistical analyses, I often lack the relevant domain expertise to substantiate the article with relevant information, and relate it to prior research in the area. Therefore, I would like to work together with people who are more knowledgeable in these fields, and write papers together. 

Being outside academia, however, often makes it difficult to find people who'd like to collaborate with me. Thus, I wonder whether there is some international community of independent scholars. Preferably, this community would be backed by some website through which I can find like-minded researchers who'd like to work with me. Ideally, the website would have some kind of SE-like interface, through which on can propose ideas for articles. Then, others can respond to the idea, and "matches" between researchers can be made. 

Having a background in mathematics, I know of the so-called Polymath Project for massively collaborative mathematical projects. This is related to, but not exactly, what I'm looking for. For one, it is restricted to mathematics. Moreover, it is not especially geared towards independent researchers, and the concept is not to have some kind of match-making system for researchers and their ideas. 

Questions


Do you know whether an international community of independent researchers exists? 
Is it backed by the website I've just described? 
Are there any projects like this currently under development, or have they existed in the past? 
If it doesn't exist (yet), do you think it's a good idea to create such a community and website, and do you have suggestions to make it a thriving, long-term community?
IGDORE, a large organization for independent scientists, hosts an online forum titled On Science and Academia. This is by far the largest online meeting place for independent scientists to my knowledge. IGDORE membership is not required to participate. I am not a member of IGDORE, and I have seen others with traditional university affiliations participate as well.
I've found the website useful to meet like-minded people, and I believe they would be receptive to requests to collaborate on a particular idea.
