I noticed when I was registering that there is no audio option. I have friends in their 60’s with reading issues and they find the codes hard to read and they get very frustrated. Usually they end up not joining that particular forum, which is a pity. I think you are doing yourself a disservice by not having one on the registration page.
Thanks for your suggestion. I’ll look into this – I am not sure if there is an ‘off the shelf’ option with the CMS that we use, but I’ll certainly take a look. In the meantime, I’ll add a link so people can contact me if they have an issue with the security code and I can then setup their account manually.
