I was wondering whether the admin team could do a weekly email to all members listing new releases, new reviews on the site etc, giving links to the relevant pages here.

I, for one, don't come here often enough, and a weekly prompt like that would almost certainly get me here at least once a week to read about new stuff. We have the Wii, DS and 3DS in our household so news about all three is of interest. Plus we'll definitely be getting a Wii U, so I'm also keen to hear news as it gets released about that as well.

I know forums are able to set up a weekly email, so I feel that you should be able to do it, and it should increase activity here, as more people visit more regularly. I hope you agree.

The RSS feeds deliver all of the updates, or you can individually select to receive news, reviews or comments.
_{if you select latest updates you won't get comments}

That is a good idea. +5 points to you, good sir or ma'am.
You could also have weekly "Talking point" subjects that you list in the emails.

I've never used RSS feeds in my life before, but I've just subscribed. I've had to show the Bookmarks Toolbar, which is usually hidden, and I have to remember to click on the links, I assume, so it isn't as easy and convenient as an email. we'll see.

If you have a Mail client, such as Thunderbird, you can have both your e-mails and rss feeds in one place.

I'm afraid you're confusing me at the moment. Yes, I use Thunderbird. How would I set that up?

This is everything you need to know on setting up RSS on Thun...
_{hope that helps}

My God, that's confusing. I created the account, but lost the plot totally at subscribing to news feeds. Sorry. An email is WAYYYYYY easier.

We're looking into monthly newsletters which I think might work better than a weekly affair.

Don't forget we also post our updates via Twitter and on Facebook if they're more convenient than RSS

Ah, somehow I had unliked you on Facebook, so I have rectified that. Thanks.
