Have been reading the recent discussions on protecting user's privacy on this forum and thinking about everyone's concern about the issue, I feel that the best way to have it resolved would be to provide the registered user an option to post or open a thread as "Anonymous" or with their own IL identity. This way the system and the reader knows that the post is from a registered user. In case of abuse or inappropriate activity, the admins can take action, just as they do in case of bad users. Many times, a user may want to put their opinion and wouldn't want other IL users to judge them. So having this option will also provide a mechanism to freely express opinion without being judged. Also, users will not have to create multiple user ids. I believe this would resolve concerns for everyone.
