Community builder login with pop-up

Hi,
I use the component Community Builder with his login module in this template. I setted up the option "Login Message: Show" in it.
I would like the "welcome/login message" in a pop-up but after login the message is shown in a static module into homepage.
It is possibile to open this login/welcome message in a popup?
Thank you so much.

You need to modify override mod_login module which you can find in template/html directory and paste there you login code/script.

Thank you for your reply.
But wich code must I paste there?
Thank you
