This was a MUST HAVE for our forum, when we migrated from vB over to XF. While on vB due to COPPA, we always collected DOB information. However, after realizing that one can include a 'I am older than 13' statement in our Terms of Service agreement we chose to no longer require DOB info.
Having the DOB field show up during registration, just caused confusion…mainly because the 'not required' sub-script notice is so very low-lighted, it's essentially invisible. Yet, the DOB box is clearly present and seems to require being filled-in.
This add-on allowed us to simply remove the DOB box from our registration page, which streamlined the process. Many Thanxx!
