Suggestions to turn an "accepted, pending revisions" into an "accepted" As far as I understand "accepted pending revisions" is not the same as "submission accepted".

What are some important things to keep in mind while revising the submission in order for it to be finally accepted? Which have been the most useful to you?
When they say that, they send you a list of suggested revisions (or several lists, one from each reviewer).  Just follow those suggestions.  When you send it back, explain which suggestions you followed, and which you did not (and why not).
