You can mostly blame it on The Pirate Fleet, who did a similar thing as I'm doing now, they just picked the wrong time. A few of us had reach significant milestones in other projects, like Folding, or where getting fed up with unreliability of SETI on BOINC, so we decided to give them a stern chase in Rosetta - as you can probably see from our recent stats - which has re-ignited our teams interest in Rosetta and BOINC in general.
Feel free to pop over to the OcUK forums to say hello.
If you feel like making a race of it, I'm sure the Rosetta project would appreciate your contributions.

All the best
