Hello, new here, and I don't quite know if this is the appropriate place to ask this question, but I did a quick search and didn't find any topics about my question. I am running a collaboration website, for people who have certain skills, and want to trade the use of those skills to others for the use of their skills in return, to accomplish something that they weren't able to alone. To that effect, I am looking for collaborative software that allows users to work together to accomplish a common goal, or add their input in an organic way. I am already using a sort of hub software called Cyn.in, I just need application specific software. Say, and this is just a rough example but one I am hoping will illustrate my point, I wanted to find a piece of software where users could edit a word processor document at the same time. Not considering all the trouble getting people to work in a group is, and all the chaos that might ensue without proper rules and etiquette, what "Type" or "Genre" of software would I be looking for. I can do all the research myself to find the individual software, but I just need to know which corner of the world to look in first. By what name might I search for this kind of software. Everything always seems to point to some kind of centralized, all-in-one solution (that doesn't ever have all of it in one, or else I wouldn't be here) like what I'm already using (Cyn.in). I need something along the lines of this proposed Drupal module in this link (sorry if posting links is not allowed, but this proposal really explains my needs, within the context of music composition) https://groups.drupal.org/node/20920 . I'm just wondering if this specific type of software has a name, so I can go on with my research. Any help will be great. Thanks.
