The create user page has the following text for the re-captcha entry:
Please type in the text or number(s) below.

openlibrary/openlibrary/templates/account/create.html

Line 83 in 0118ddb

<div class="label">$_("Please type in the text or number(s) below.")<br/><span class="smaller lighter">$_("If you have security settings or privacy blockers installed, please disable them to see the reCAPTCHA.")</span></div>

Should we make them match?

Updated per @hornc's suggestion, although it doesn't appear to be in any danger of getting merged any time soon.
