I think it's better to have a newsletter and a team for this from AS. So that we can have Avi/Sig/edit of the week.
The newsletter can be done just like in other forums but here we have our own personal touch.
Some of the things that can be included are;
Sig/avi/edit of the week.
Some updates from the forum
Some contest and there results can be published ( as it is we are having many contests in the forum, this will be one-stop for all of them)
Coming to pic gallery, we have so many different things to keep update pics in this forum, so we can organise a team to look into it and update and index and this can be shared weekly.
We can even have a comic type of thing in the newsletter.
