Sorry, I was being flippant but I hadn't actually realized you were the one doing hte most recent up-to-date chapters as well. This is fine and makes sense for people that want consistency.
My comment was with me mistakenly believing that someone new popped up and started working from the beginning on a series that is as far in as it is. It seemed crazy that anyone would re-start a semi-obscure series and offer duplicate chapters instead of new stuff. I hadn't considered it was you back-filling earlier chapters you hadn't worked on originally.
If that's the case then by all means carry on.
