Restrict registration multishop ps

[decoratureforma.com]

Hi, this is first time I do a search in this forum, I hope to understand why I am using a translator xD.

I have a web Multitienda Prestashop 1.6.5, and professional www.myweb.com www.myweb.com /.
I would have a different registration form for each web
To www.myweb.com normal registration form and the original module prestashop.
www.myweb.com/profesionales that can not automatically register that I have to validate first.

Go mess.
