in reply to RFC: Algorithm::CouponCode

Can you avoid 1's and O's (that's the letter oh) as well?

It looks like you're not using I's and 0's (eyes and zeros :) ) but removing all the possible glyph confusions will probably help reduce errors, and it doesn't cost you that much of the space.

I just read the "About Couponcode" tab - the autocorrect is a very nice feature, but it might be worth mentioning that feature on the front page, so the customer doesn't worry while reading the code...

    After reading all the docs, I'm impressed. You've covered all the bases very nicely!

    I'd mention the auto-correction and the meaning of the green highlighting on the front page, to keep people from leaping to the same conclusions that jethro and I did.

      Thanks - I've added a mention of the auto-correction on the front page of the demo.

      In a real application I'm not sure that I'd bother mentioning it. It would be nice if there was some easy way to reassure people that they didn't need to stress about upper/lower case and whether it's a '0' or an 'O' but that would take words and people don't read words.
