acceptable to do this..?

pwd

Supervisor asked me a week and a half ago if I wanted to present a paper at a conference in September. I said yeah.
Since then I've been spending most of my waking hours programming on the project, in preparation for a review meeting with the funding body. So I haven't looked at writing anything. I see the deadline for submitting an abstract is tomorrow.
I've emailed my supervisor asking if he wants to meet this afternoon. He's good for responding and meetings etc, but there's a good chance I won't catch him at such short notice though. I don't know exactly what he envisaged the paper to be on, since there are a few possibilities, or if he had a specific subject in mind. It's a commercialisation project, so the amount of detail that should be published at this point is something to be a little cautious about.

So my question is, is it acceptable to submit the abstract without putting it in front of him first?...or at least more acceptable than not submitting at all? Alternatively, I could probably bring in a postdoc on the same project as a co-author [as well as my supervisor]

All I can say is that if it was me I'd be very wary of doing it myself tbh without running it by him or as you said the postdoc...

edit: all fine now cheers
