That's actually REALLY nice. It's been a royal pain in the ass just trying to read up on a specific character or sub-series, with your usual torrent sites etc offering rather incomplete collections, if you can find anything at all.
So for comic enthusiasts, this is probably the way to go, if the site(?) is doing a good job making the archive accessible enough for people to search through and read stuff.
Now, the most important question: How complete is it really? Is it really everything or still "growing"?
Too bad its Credit Card only, otherwise I might have given it a shot.
