I'm not sure whether it is suitable for inclusion on the list, but the UK Steampunk Website is opening its doors.
It's somewhere for all those of us who live in the UK to get together, to talk to each other, to plan things and to promote things. I'm hoping it's going to get all the separate groups who chose to live under the Steampunk banner, and just happen to be sharing the same geographical set of islands, talking, sharing and inspiring each other. It's specific nature should give it a focus which isn't possible--or desirable--on a forum like this and the openness allowed by the site should make it more accessible than an e-group. That's the plan, anyway.
The url is:
www.steampunknetwork.co.ukAs it deals specifically with Steampunk in the UK, it's appeal to international members of the community might be limited (you're quite welcome to join in, but you may have to travel a bit for the events and gatherings...). Still, if it is deemed suitable for inclusion, I'd be happy as a dandy.
If I'm barking up the right tree, the wrong tree or the wrong part of the right tree or whatever, let me know. Of course, if you have something you want to share with the world, create an account and post it up!
