Why there are some Posts by Guests?

While browsing the forum, some of you might have come across posts / threads by Guests.
For example as in here:
http://www.indusladies.com/forums/si...is-my-end.html

Immediately you must be wondering:

• How Guests are able to post in the forums?
• How Guests are having post count credit to their account?
• Is there any change in the permission for Guests recently so that they are able to post?

Here are the answers to the above questions:

During the routine cleanup activity, we found some users with invalid E-mail id so as a part of cleaning up, we changed their status to "Guest" so that only if they provide a valid E-mail id will they be able to participate in the forums further.
Now coming to the answers:

• It is not the posts of the Guests, but the post that were made when they were Registered members of the forums.
• As mentioned the post count to their credit is because of their participation when their status was as active & registered members.
• No there is no recent change in the permission for Guests - they are not allowed to post or participate in the forums as ever.

Once these members change their mailing id to a valid one, their status will also be reverted to "Registered Members".

nice share :)
i did have these kinda doubts in my mind :)

Thank Laxmi for the post, I saw a user as guest and was wondering how can this happen.
