Trying to install the pyForum named Forest - bricked the install

I did

sudo /opt/piratebox/bin/install_piratebox.sh /opt/piratebox/conf/piratebox.conf pyForum

then

 sudo nano /opt/piratebox/conf/piratebox.conf

Looking for "the line starting with FORUM_LINK_HTML"

annnd it wasn't there..

so then, following the instructions, I did

sudo reboot

Then the Pi no longer worked. I already reflashed my sd card and edited stuff to get myself back to where I was before trying to change the forum.

I would really like to use a different forum, preferably one that is mobile responsive, but I don't know how to add a different one in.

Mh, too bad it bricked your installation.
The pyForum will be removed in a future PirateBox version anyway.... especially if you wand a more responsive version, you need to modify the PirateBox yourself.

Sorry for the bad news
