Dear forum admin.,
Your CAPTCHAs are kind of hard to read; the letters are too small and there is too much interference (Is that an 'E' or an 'F'? Is that an 'H' or two 'l's or two 'I's or two '1's?). Could you please switch to:
A. Bigger letters
B. The photo lineup CAPTCHA
C. The "I am not a robot" CAPTCHA
Regards
