MessageBox question

Hello all, I am new to the development of install programs, but I find that it is something I became interested in almost instantly.

I was wondering if there is a way to add a line break in a messagebox? Here's an example of what i'm talking about:

Instead of:
Name and Password accepted. Thank you.

It would look like this:
Name and Password accepted.
Thank You.

Is this possible?

Thanks for the help!

See NSIS manual,

Oh I see now. I was just doing \r instead of $\r.

Thanks for the help.
