I'd just like to ask about the stipulation in the sign-up that we don't 'make reference to already published works you've done (such as "this is the second instalment of my series X") in this summary'

I have a WiP that I've published a few chapters of on AO3, and I'd love to get a kick up the arse to finish it. Would it be OK to sign up with this as long as I don't mention the title or link to it in my sign up? Or should the works for this challenge be entirely unposted (I've got one of those too, so I'm still good to go!)
