I went ahead and decided to add the Maxis sim spouses to the list after all (it was feeling a bit incomplete). So the sims added to the entry were the generation 1 and 2 main house spouses (Fergus and Vernon), Ivy (Hector's wife), Allyn (Lorens' wife), Lee (Ravi's husband), Donald (Phlox's husband; not a Maxis sim but it was time for him to be added anyway) and Amin (Ruthenium's husband).
After I tracked down (most of) the CC items used in the sims I've upload, I've finally gone and added (extremely long in some cases) CC reference lists at the end of the "Download a Random", "Download a Harker" and "Gone Sims" entries. (I'll be updating those every time I add more sims to them.) It's a relief to finally have those more organized. :)
