These are marktrade's scans so I am guessing 300DPI. I don't change resolution/DPI settings at all.
I appreciate you and E-Day follow the Meppi code of editing the heck out of things which is fine and dandy. I follow the "get as much up as possible" practice nowadays as one, I'm old so time isn't on my side and two, I would rather scan than edit. marktrade put up a swag load of raw scans for people to edit, and apart from Depressor doing a few Super Play's nothing else has happened so I thought I'd whack a few up and at least they would be presentable. That's partly why I didn't upload them here but rather make them available via my Google Drive account in the event that someone wanted to edit them more before making a proper RM version. However, I'll stop that and let someone else do RM versions as of today.
As for OGM, I have my scanning members use 300DPI with preferably no page size dimension adjustments if they can get a mag into 400mb or less. However, people have different scanners and PC's so at the end of the day I have to be flexible as I'd rather have magazines preserved than not and driving contributors away by forcing strict guidelines becomes somewhat self defeating if they decide to stop scanning. Given how few people contribute I am adopting a tolerant approach to things.
