New user captcha

[engineertype]

It was pretty difficult to register for this forum. I struggled to get past the captcha.

"Enter the first and last three characters of the following expression into the box: rE#U3as!@^5:
This question is a means of preventing automated form submissions by spambots."

Technically the right answer is "r^5:"
Assuming you mean "first three and last three" then the right answer is "rE#^5:"

The answer that finally let me in was "rE#@^5".

Can you please remove the ":" following the expression, and add the word "three"? so the challenge becomes:
"Enter the first three and last three characters of the following expression into the box: rE#U3as!@^5
This question is a means of preventing automated form submissions by spambots."

Thanks,

Peter
