You wish to upload a preset?
This is simple, merly log in to the yellow box at the top right of the page next to the banner, once done you should go to the user panel, here you should have a list of your characters, scroll down in that box and you will see underneath the character list that you can then "upload" a preset file, simply click upload, find the preset, then hit ok once you've clicked it.
once uploaded anyone who wants to see the preset will need to completely re-start FH (this is assuming they have the Preset sync set up) If they still cant see it after a re-start, i suggest that you then re-start your FH, this usually fixes this problem.
If this is not what you asked then i can only presume you are looking for the forum thread which is found here >
