Some notes:
If said missing fics are in thread X, their absence can be accounted for by the fact that I haven't archived anything from thread X yet.
Otherwise, I may have simply missed them when archiving the previous threads. It happens from time to time. Note that I'm especially likely to miss any ships that aren't spoiler'd as I completely ignore the vast majority of the random jabber in the thread(s) while doing archive updates, focusing on hunting for spoiler boxes. If your fic isn't in a spoiler, there's a good chance it won't be archived.
As my available time online has been drastically reduced in recent months, I could use a little assistance in maintaining the archive. If either of you would like to assemble a list of links to the missing fics and PM them to me, I'd very much appreciate it and will include them in the archive ASAP. Otherwise, I honestly don't have the time to trawl through the previous threads hunting for them. Sorry...
