Coin Makers come and go in this space and their websites often disappear with them. To help preserve this I have been archiving as many makers sites as I can. I actually started a couple of years ago with a couple of sites but the most recent captures have a lot more sites saved.
You can see the current archived sites here: http://archive.coin.community
I have been using HTTrack to archive the sites, it works ok most of the time but some of them don’t save properly. If anyone has a better way to archive let me know.
If you want to create your own backup this is the current list I am using:
