In the Joomla USER area you can add custom fields to the user registration. I am adding a couple fields to collect Organization Information, for example company name.
These fields DO NOT display when using Eximium or YouGrids. The fields DO display when I switch to Bees or ProStar.
Are you sure your are posting in product assigned forum?
What is your CMS version?

Is this personal or client website?
