Hello,
is it possible to get information if a specific skin is already uploaded on LFS World without opening LFSWorld?
For example:
lfsworld.com/skinname.gif
Thankyou

Nope. The skin repository is not publically accessable in any way except through LFS.

Will that change soon?

But ... HTTP Traffic is such a cool thing *hint*.

no, it will never be publically available.
