I have this tutorial left over from back when I was part of RS.
As far as having a readable chapter goes, I know there are a few on MangaFox that did some but it's pretty crappy and uses LQ raws. We have a standard of being a high quality group and this is something we stick by. Personally, I don't touch anything unless I can look back on it a few years later and be proud of my work. I even re-scanlated 12 chapters of Yongbi when I bought the HQ Korean raws because I wasn't satisfied with their quality. I guess we just have different philosophies when it comes to scanlation.
Anyway, if you want shit to practice with, I have Dreamland raws of a previous volume right here : https://www.mediafire.com/folder/6yr...f90k/Volume_08. (I'm the scanner)
