I have submitted a paper to Proc. Am. Math. Soc. My advisor said to submit to this journal. It's been over 3.5 months with no response. I have made several edits to my paper, but none that essentially change the structure of a proof. The original email contained the following message:
Submission of unrequested revisions is discouraged. If SUBSTANTIAL modifications are absolutely necessary after initial submission, the above link can be used to resubmit your article. Please limit the use of this link to one resubmission.
Based on these words I would not resubmit, but I am wondering, since it is taking so long, should I just send in the current version to perhaps get the attention of the reviewer?
