Firstly I want to say that I the presentation of this forum, and its probably a small thing but I hate Captcha with a passion (and its only used in one or two places on vBulletin forums/boards), but if I had my way all sites would use some of the many more user friendly options to catch bots and such registering or trying to request their user/password.

Here are a couple of examples -

Code:
https://www.keycaptcha.com/
https://portal.areyouahuman.com/installation/vbulletin
Personally i prefer the second, and it may seem like a big moan for such a small issue, and it is of course your forum to run as you see fit... But I really do hate it hence this long winded post

Thanks for reading...
