Hi sookie,
There are a few reasons why we have the moderation for example:
We have quite a bit of spam that attempts to make it onto the boards (even with filters to prevent this) - innocent looking threads which aren't very innocent. By moderating we are able to prevent these making an appearance on the site
There are some threads which call for us to add a comment - if they all go on as normal, we can't see these and are unable to address them.
In addition to this, and perhaps the most important, we want to make sure that members don't accidentally slip up and give out their personal details in what is a very public forum.
I appreciate that it is frustrating to some members as they would like to chat throughout the weekend. Where there is mutual consent, we are always happy to pass on email addresses so that you can chat away from the community.
Kindest regards,
Julia
