First post, after discovering this site only an hour or so ago ...
In other Citizen Science fora I've seen a few examples of someone keen to do some work/research that goes beyond the sorts of projects we all know and love, and which is also not necessarily a Community Project of the kind mentioned earlier in this thread. These people are - if memory serves - not professional scientists, though they may have a job, or have training, or simply a passion, which may be directly pertinent; they may be a dab hand at Java perhaps, or can make Photoshop sit up and beg, or know everything there is to know about Messier objects. Would this kind of thing lead to anything publishable? I don't know. Would it enriching for this community? Definitely!
As far as I know, there is no venue for such folk; they stumble on with their pet project, and often produce something quite interesting, but it's almost always a lonely path they tread.
What do you think?
