So this looks quite embarrassing on my behalf, eh.
Basically, I got told to come on TS and informed that before I resigned (without any notice), I was on the watchlist for admin. After a brief discussion with everyone in the meeting and a little thinking through, we decided I would still be able to maintain good activity at the same time as resigning, and that I was holding myself to quite a high standard of activity. So, I'm going to give this a try and if PERP is a big issue with revision; I'll think it through a little more.
Sorry to whoever's hopes I got up with this post!
