When exporting, it will list all the things you've exported in the map, make sure you've memorized what has been exported. Make sure you have all .fho .fhm .fhs [Basically everything that you exported that begins with .fh] and put them into a folder. Along with the other things that you exported.
Make instructions in Notepad or any other word document with what and where everything must go. For example;
''Map made by ____. Please do not claim this map as your own. Any map claimers..etc.. Here are some instructions on where these files should go:
All files MUST be placed in Local Disk (C:) >> FeralHeart >> Exports.
Then restart FH and enjoy!''
Then save & put the word document inside the folder.
Upload the folder to Sendspace (http://www.sendspace.com), Mediafire (http://mediafire.com) or any other file sharing sites.
