Right, I have made a separate AO3 account for my podfic:
Luzula_podfic.
I wanted to be able to see my podfic fandoms and tags and statistics separately from the ones for my fics, and if I used a pseud for it, then the statistics would still get mushed together. Plus, you can't easily link to a pseud (as above). The drawback is that my podfic username has to be qualified with "podfic", while my fic account has no qualifier, like fic is obviously the main and most important thing I do, which is not true. But I created a "Luzula" pseud at the podfic account, to counteract this as far as I could.
Er, don't expect much to go up there soon, though--there's just a couple of podfics that had to be posted to AO3 for challenges, as well as some collaborations that other people have posted. I'm waiting on separate media categories at AO3 before I upload the bulk of my stuff, because I have
tons of podfics, and uploading and then having to edit afterwards would just be unnecessary work. My
podfic index is still the best way to find my podfic.
