I have a group of online workers that need to work on a common task , the notifications for the work to be done are also common like the todo lists, wikis, docs etc. What I want is enforcing anonymity among the workers so that their identity is hidden from each other , yet they can see each other's work\tasks under pseudo aliases. Although communication among the workers is encouraged but sharing of identities is not. This is required by the nature of the project to not know each other's identity , so that work of the individual workers wont get copied\contaminated with each other(Kind of researcher study requirement where participants should not know each other).
What worked for me till now
I am currently using the email Bcc to maintain anonymity between the workers, But it has its restrictions like others cannot see other people's work, redundant threads etc. Inshort it become cumbersome to manage threads in BCC.
I have seen, Wiki, google docs, wiggio etc and may be I am missing something that I cant figure out how to accomplish this?
