Speaking of my D&D groups, time for an update:
The Saturday game seems to have settled into a reasonable pattern. I have brought my Warhammer campaign to a close: the Company of the Black Hand uncovered the corruption at the heart of Walkenburg and rooted it out; in time they were able to depart the town as heroes, albeit ones wounded and deranged by their experiences.
I have taken a step back from running games with this group for the time being; one of my friends is instead running "Dark Heresy" for a while. It's an interesting game; we'll see how it pans out.
The group also seems to have settled into an almost-monthly meeting cycle, which seems to work reasonably well. It's not ideal - I would prefer to meet more often - but it's much better than our previous arrangements, and actually means we may meet more often this year than in each of the last two. So that's good.
The other group is currently in something of an interim period. We don't have any ongoing games running, with a couple of new campaigns about to kick off. Despite this, the group seems to be quite busy: we've had a number of one-off games, we have a cinema night planned for Friday (going to see "Your Highness"), and we're in the process of moving the site from Meetup.com to GroupSpaces, due to the changes made to Meetup.
In the middle of next month, I'm going to be starting up a new campaign, "The Eberron Code", which I've described as "like The Da Vinci Code, but starring Indiana Jones, set in Eberron, and better written". There seems to be quite a bit of enthusiasm about this one, and I'm rather looking forward to it also. I've had a good number of ideas for plotlines and adventures, have a good idea of the campaign metaplot, and am quite keen to run a game again.
So, it's all looking quite good, really.
