Thank you! I was able to omit 2.
1. Is it alright to abbreviate the conference for additional posters if I use the full name first? Ex. "Super Amazing Research Conference (SARC)"
2. I have two conference experiences, one national and international. However, the international one was hosted at my local university, so I was involved with managing and organizing. Would it be better to use the international conference experience than the national conference I was not affiliated with, even though our university hosted it? Or does it not matter at all
