How I do save a current plugin under a different name (aka "Save as") I have a working mod on steam, but I like to tried out different bugs fixes that might break the mod, but I do NOT want to mess up the live mod? So re-saving a mod under a file name, how?

The CK doesn't have a Save As option. What I do though, is just use Windows Explorer to copy the current ESP and rename it to what I want, since the CK doens't lock the file after it loads it.

cool, thanks How does upload to steam work? Will CK tried to d/l the mods pic and info or will CK gave you a blank profile to fill out for steam?

The CK will give you the blank template. The picture you set when you upload is the "main" pic used by Steam and can't be changed in Steam (but can be changed with the CK).
