Website field unrequired for visitors

[na4]

I see four options in Jcomments for the "website" field: disabled, unrequired, required for guests and required for all. I was wondering if it was possible to change the code so that the field will appear for guests only, but as an unrequired field. Non-guests will be linked to Community Builder on my site, so there's no point in having a website url linked to their name (instead I've got a link to their CB profile); and not all visitors have a website or will want to enter one in.

If you let me know where/what to change, that would be great!

Thanks

Ok, this is good idea! I'll add this into my todo list.

Thanks, this would really improve things on my site.
