Greetings. Now I have created my first test for a custom specie,

wouldn't it be nice to have an option to use a custom specie file just like a map skin one?
Unlike the map skin, not at local level, but for all other users to see my own specie (no need for all 4 to have it active). Example: instead of using a flapper, using another one I create. However, only my char would be affected, it wouldn't affect any other flapper, but all other users would be able to see it. It is, an unique personal specie for the user who has it activated, not to replace all of the flapper specie for the custom one.
Limited to a single custom specie for each player, to avoid custom files SPAM.

Not sure about how to manage it. Maybe uploading it in the same way you upload a custom pic for the forum avatar? It should also check the file resolution to fit the 1088x48 race.png (and 544x24 small) images.
Just suggesting, the brains behind the MULE are the one deciding and doing.
