I submit a paper to a journal which allows to publish the preprint as a working paper. After submission, I thought I can just take the version I just submitted and publish it on ResearchGate. But then I thought that it might be problematic to use the same format I used for submission, since then everyone knows to what journal I submitted (or at least, to what publisher). Then, if my paper gets rejected, everyone knows that.
Is this an important consideration? Is it important to change the format of the paper before putting it in a preprint archive?
