There's actually one other thing I wanted to ask about if anyone's got the time. A couple of the larger doujinshi I bought actually turned out to be compilations of several smaller doujinshi, some of which have already been uploaded to sadpanda. I was wondering whether I need to go through the effort of rescanning and cleaning these parts, or if I can use the preexisting scans and just do the new parts? Also, should I upload the parts individually as I finish them, or wait and upload the whole thing together?

Edit Anon here. I had a quick question regarding one of the doujinshi I plan to do in the future. This one here is a collection of Battler X Beatrice works by Slime Kikaku, and is over 150 pages long. Of the 10 stories included in the bundle, 4 have already been scanned and uploaded on sad panda in the past. Is it alright for me to just reuse the preexisting scans for those sections rather than doing it all over again myself? Or are there restrictions on that sort of thing?
