I am very glad to become a moderator for Computational Science SE. Will try my best to be a good one. In addition to the routine moderator work, I am certainly interested in making Computational Science SE more convenient, friendly to use, and, potentially/probably, attract a bigger audience.
I certainly would initiate a tag cleanup (I hope @GertVdE would join me and other moderators) soon.
Continuous revision/refection of "on-/off-topic for our community" is also among the items I am going to watch out for.
I personally love to work on the old questions (there are some gems among the unanswered) and will continue this effort.
I welcome all the suggestions and ideas you have. To share them, I would encourage you to use this Meta. And if you are really-really anxious for privacy, it's not too hard to find my contacts as I use my real name and list a personal website on my SE profile page.
