So I was curious if there was an online comic collector databse that didn't requre any additional software to download and came across StashMyComics.com. I like it because it's easy to use as well as navigate. Plus, it doesn't take long to update my collection nd it gives me a reason to go through my boxes of comics again and possibly find stuff I didn't know I had. I highly recommend it, especially if you're looking to keep track of your collection.
