Hi Milli05,
What i understand in your question, is how create a link, so the user can edit his "custom" profil.
As mentionned by jrmo, you have to set the right on your form. But for the link, as Bridge is enabled, create a new Menu item type, select 'User Manager' > 'Edit User Profile'. That's will drive your user directly to the form edited with his own custom profil. At least work for me under Joomla 3.3.3 with Seblod 3.3.7.
Hope this answers your question....
