I'm a CS PhD student, I'd like to submit something at a conference that has a deadline next year. I mentioned submitting to this conference in an email to my advisor and after looking at it, they told me in-person it was not a major enough conference to submit to. The conference is comparatively new, but it is maybe the largest one in the subfield.
I briefly mentioned to my advisor that I thought it would be good for networking (and that also I know a few friends nearby the conference). I didn't think of mentioning in the meeting that I've reviewed for the conference's sister workshop, and trust it's a good conference. Moreover, I think many of the organizers are well-known, and many of the proceedings are submitted by very well established groups.
Even if I don't submit this year, I'd like to convince my advisor that submitting there in the future will be beneficial. How can I approach this topic next time to convince them this is a good idea?
