You note here that there is a *conflict* with Sunil's series, but what you actually did, as far as I can tell, is base your series on top of theirs? If you're going to do that, at least point it out so that reviewers don't have to figure out what your intention was :( Better yet, for the sake of our automation in particular, don't do it at all.
