Thanks for the nod of appreciation, but I am just glad to have found somewhere I could add to the site given how great it is (and a thank you is deserved for everyone who has added in whatever way they can, or even just become a great part of the site community). Finding this site a few years ago is what really drove me back into collecting again.
As far as the Magic sets go - if I have a card from the set I add it. I know there are some sets/duel decks I haven't been able to get around to for uploading a checklist, but if no one beats me to it - it's on the list of "to do" items for me. As are scanning the cards I do have. I have scanned a few, but have many that I can add, I just prefer keeping up with the blog and getting new cards cataloged for now, but plan on scanning through and adding what I can starting later this year.
For the card backs that are the same - I wonder if there is an easy function for admin to just add these if directed correctly (for example - cards 1-100 and 110-200 all have the same back) - just for the ease and spped of adding them (as you are correct, the points really don't matter - it's knowing what one has contributed).
Regarding the PIDs - do let me know where that resolves, and any other recommendations/resolutions with Admin. Frankly, I have barely scratched the surface on that part of the workings of the site. Checklists and scanning I can do (and am comfortable I won't screw up).
Anyway, back to my relative silence for now, but thank you again, and do let me know if you find anything I should correct or change going forward on set set lists, etc. :)
