I do them without caps. Just be aware they're always 6 characters. If you have more or less than 6 numbers/letters, that's when you should double-check what you typed.
I know the Rubin hits are dwindling but I put together a small list of catalogs. If you guys would like to add some here is the document. https://docs.google.com/spreadsheet/ccc?key=0Ark5mXZ4foD1dERtX09ibWVCSzhfVnpBckhrYnhvVlE#gid=0
So is that my problem. I can't picture messing up 9 times in a row. If the HIT you're on is being took by another person before you can enter the captcha? Like say you have to enter one with TWO LAKES, since they go so fast, people are taking the HIT before you can enter the captcha?

The only thing I've gotten approved out of today's HITs so far is the one Rubin HIT I did that took me like 7 minutes.
Haha sorry I didn't mean they were all Rubins. I only did probably 30 or so of those. My brain became mushy after doing them for too long.
Check out your quals, it will still be 99%. The dashboard is rounded so it can read 100%, but your qual will remain 99%.
