Interesting thread.
So... most of you suggest against "guest" posting.
Here is what I am planning to do - I have a very exclusive members website. To become a member, you have to pass several "tests" that cannot be faked. This includes a voice call to your current employer.
There is a ton of brain power in that group, and there are some who cannot make it because of one or an other reason. I would still like to offer these non-members a sort of a guest pass. Register as a user, yet not have full access to everything internal. I guess this is what Atomica was talking about. The requirements to register as a "guest" would be seriously reduced, allowing the "guests" to post/read/mingle in designated areas with the full members.
Does this still sound like a bad idea?
