ok, perfect. for repo format would be like this below (assuming add-on name is "skin.xyz" and version from addon.xml is 1.0.5).

1) if texture bundle, remove individual files from below media/ directory
2) folder with skin (addon) contains .zip file which is prepared from parent directory:
zip -r skin.xyz-1.0.5.zip skin.xyz/
3) changelog should be named the same way with version. otherwise XBMC will not be able to display it so:
changelog.txt -> changelog-1.0.5.txt

you can then share .zip with me, I will do the structure by unpacking it etc.
