I stumbled across a site via Wayback that had a lot of SGA and SG1 fic. I tried hard, but was unable to find any kind of index or front page. Problem is, most of the stories did not have an author name attached. I've done a title/fandom search at both AO3 and Squidgeworld, and none show up. I'll list titles and the URL that will lead to the story if you put it in Wayback. If anyone knows the site front page or index page, and/or the author(s), please let me know. If not, and you save stories, you should grab these; you might never find them again! Most are slash of various ratings.

The author sage_theory (papersage) (Meg Freeman) at AO3 — https://archiveofourown.org/users/papersage/pseuds/sage_theory— did put their name on their fics. If you read that author, they have two SGA fics on this site that haven't been transferred to AO3 —
Know Me Broken (SG1 x SGA) http://www.paper-hearted.org/prose/knowmebroken.html
Hospitality Sweet http://www.paper-hearted.org/prose/hospitality.html
Also 7 that are SG1-only. If it's allowed, I'll add those titles and URLs if someone wants them.

Thanks for any help you can give.
