Need additional seller info on seller page

[Stefan Kaufmann]

Hi, we are looking for a solution to add additional seller information (e.g. with an additional field) to the seller profile page.
I've found out that when adding a new registration field (type: textarea), this field does not show on the seller page, i.e. it can not be added with the browse form. Somewhere in the forum I*read that this is because a textarea field would be too big and perhaps be in conflict with the page layout.

We would need an additional field to add the "Imprint" Information. In Germany this is a legal requirement for any commercial seller, even on a car marketplace. As a workaround we could use the "About us" field as this is shown on the seller page. But we are wondering whether there is no other solution to add an additional filed on the seller page.

Anyone has tips or suggestions on this?
Many thanks.
