Hi all, I'm a physics postdoc and I recently got an invitation to submit a paper based on some conference proceedings by what was already our target journal for the longer form paper for that project (Q1 journal, highly respected in my field). I'd never gotten this kind of invite from a non-predatory journal before, I was wondering if this was common and whether it made any kind of difference whether a paper was invited or not like it does with conference talks. This is an original research paper, not a review - I understand it's more common for these.
