No problem at all! <3
Ah! You have to upload the fhp file that you exported onto a file sharing site, the fhp file you need will be in 'presets' in the main Feral Heart directory. You can use MediaFire for this, that's what I use at least. Depends on the person! There's also Dropbox and Google Drive to name a couple others.
After uploaded, give your friends the link and they should be able to see it after downloading. <3 If you uploaded the fhp to Preset Sync, the preset might simply haven't uploaded yet for them.
