OK, thanks, I'll have a look at that.

Since the app is personalised (i.e., it shows you only the feeds you've subscribed to), I can't think of any way around having a login for long term use. Do you have any suggestions?

Send the user to a secret URL the first time they use it, which they can bookmark. Give them the option to create a username and password so they don't have to remember the URL in the future.

Nice idea - thanks!

I get 'Couldn't validate the captcha, please try again' when trying to register. But there's no captcha visible. (OSX / Opera)

Do you have javascript enabled? I'm using reCaptcha (although I'm considering dropping that in favour of something simpler - "which of these pictures is the right way up?" or something like that).

Incidentally, you will also need javascript for the password entry to work - your password is hashed (SHA1) before transmission.

Otherwise - could it be some sort of ad-blocking extension maybe?

Ah yes, was going to comment on that too.. Why do you have a captcha? Are you having spam registration problems?

As captchas are a hassle to people, I wouldn't worry putting one in place until you have an issue with non-humans registering.

You're right, thanks - it's only there 'just in case'. I've taken it out.

OK, I've just tried with a vanilla install of Opera and the captcha isn't showing up - I'll fix that ASAP.

OK, give it another go - the captcha is no more!
