Alt -s, bugs me! I mean, here I am skinning, in detail, when suddenly out of nowhere, (owner/operator), an error is made.
I hit alt-s and let me tell ya, you got to remember to let off the gas (left mouse), sometimes.
Say, isn't having 50 skins to work with the freak'n the best!? I am loving it!
But I got a question, might sound dumb or lazy but, can I alter a skin once I have shared it online?

To answer the only bit I actually understood, which happens to be a question. Yes, you can. Other players will obviously still download the original version until you upload the new one, but you don't have to pick a different name, LFS checks if the file has been changed and always uses the most recent (by date modified) version.
