Age Check on First Page for Guest ?

[EsfTR]

We have a Forum for E-Cigarrets in Turkey but we need a Massage Box for Guest User withe an Age Check like "Enter when over +18" or like the same. We look for a add-on but i can not find it.

I think last chance is a add-on with a Notice Box on the first Main Page :-(

Can anyone help us with this.
