has any one see one on mine town

Several, but they've all been thoroughly scavenged by now I'm afraid. You might be able to find netherbrick, but all the wart and spawners in known fortresses are long gone.

Go through most any nether portal and run around a bit, you're sure to find one.

but who has seen one

This looks cool. I am excited to start playing on the server.

NF2?

I have. Drupe has too, but he would never admit it. <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f61b.svg?0" type="image/svg+xml" standby=":p">:p</object>
