If you want your friends to see it but not able to use it then you have to click the Export button in Preset Maker. Then send the exported file
[username].fhp (located in your Feralheart>> Presets folder) to your friends, exactly what KitkatRevolution has mentioned ^^ Your friends just place the .fhp file into their Presets folder after downloading.
If you would like your friends to be able to use it then you must give them all your preset files, such as the images and .material file, just by uploading those files (or folder) to a file sharing site such as
www.mediafire.com. Then just have your friends move those files to the appropriate preset folder (preset_3, preset_5 etc). Then they can use it from Preset Maker
EDIT: I've only just heard about this preset syncing now o: I will also try it out ^^
