You will have to download the person's .fhp file to view their preset, and they will have to download your .fhp to see yours.
'Tis quite simple.
Download their preset, then copy/paste the .fhp file into Local Disk>> Feral Heart >> Presets.
That was probably super confusing, so here is a link for further help: (:
Hope things work out!~
Getting a Preset In-Game (http://www.feral-heart.com/index.php?option=com_content&view=article&id=10&Itemid=17)
Let me see if I can make this a bit more clear(er).
Once you have exported your preset (in which case is your Nybu.fhp file), you'll need to transfer said file over to your friend in order for they to see you in-game.
This can be done by uploading the file to a file sharing site such as Mediafire or Dropbox, even Skype if you have one.
Once your friend has downloaded the file, they'll need to place it in the destination Ms. Jim provided,
Local Disk>> Feral Heart >> Presets.
Afterwards, when they start up the game, they'll be able to see your preset in-game.
Your friend will have to do the same as you in order for yourself to see their preset.
