When I was signing up for this forum (or posting), there were places to read blurry letters and enter them. There were some letters blurred so badly I wasn't sure what to enter.
I know you have to do this for security, but they are too blurred for a lot of people, causing frustration. Plus most forums don't require that for making a post.
Robertjc, you are right, CAPTCHA is a security measure for the Norton Community new users. An alternative would be to use the audio option which is also provided. Hopefully that might be a bit easier for you.
Please be sure and post any additional issues you might have and WELCOME to the forum!

I've met some where it's very difficult to know if it is a 7, a 1 or an l ; or is it a 2 or a Z so this feature is very useful
