I've been interested in learning Solresol, as the idea of it intrigues me. But I haven't been able to find anything in English to learn it from (the original works on the language are in French, which I don't know).
I checked out sidosi.org, and it shows a couple of links to an English translation of the original grammar of Solresol, but one redirects back to the sidosi.org homepage, and one leads to a message saying the site has been retired from service. Other resources are also linked, and also turn out to be missing.
So are there any resources (preferably online) to learn Solresol from English?
