Captcha too strong for users
I have enabled captcha on my site and since then I do not have any spammers, thats great!
But now I get daily emails from my users. Many of them claim, that they can't solve the captcha. I see much less registrations of normal users.
I would suggest to implement something less complicated. Recaptcha is outdated and a barrier for many people especially the older ones.
Something like http://sweetcaptcha.com/ or similar would be great
