Paradimension.com is for TGW (The Gorse Weasel) to show off things made locally (Doncaster, UK), generally they are for sale but only locally (can't be bothered with post packing etc.)
There isn't a sign up page because there's no newsletters, updates and such. There is a mastodon link to a colleague at the bottom of the page and now a contact page if you're desperate to get in touch.
