Drop me an email at email@example.com if you'd like to contribute any scans, including counter and covers. I can accept virtually any kind of image format. I will convert them to JPG and make them available here, with credit of course! Please only send scans for the front of the counter sheet, as that is all I keep. I don't run a counter replacement service, just an easy way to get a counter manifest.
Please see the Scans page for a canonical list of all the games with scans currently on SimBase. If in doubt, please don't hesitate to send them along - I'll sort it out here.
If you can, here are the guidelines I use before putting the scans online:
I've also set up an ftp site, if you'd rather upload the scans. It's often easier on both of us if you do that. Here's the info on the ftp site:ftp://ftp.thewargamer.com
Be sure to drop me an email or upload a text file, describing the files you uploaded.
