[Grace-core] blog spam moderation

[James Noble]

Hi all

sorry about the spam emails that came down the list.

I'm not sure why: I upgraded the blog yesterday after a
critical security notification, reset the anti-spam plugin,
so no idea why this started emailing out now.

Anyway: I've redirected the blog email so there shouldn't
be any more notifications onto grace-core.	At some
point we should try to get someone who knows more
about stuff to be a webmaster for the project...

James
