Does this site have a policy on it? is it encouraged/discouraged? are there any relevant legal/practical concerns? sorry if this isn't the place for it, take it down if it isn't
We do not support collaboration, nor do we recommend it. Unless you have a good contract drawn up, with responsibilities clearly defined, it can quickly turn into a nightmare. Any private agreement you may make with another member is your own business. However, you may not use this site to seek collaborators, including public postings, blog entries, or private communications. If you make such a request to a member and he or she reports it, you will be banned.
