Please use some compression software on your ESP's.  
Zip up the esp, textures, meshes, etc.
Include a readme.txt that details what is in the zip/rar file.

Make sure all the files unzip to the correct locations if a 
user unzips them to Data Files\

Textures should go in Data Files\Textures\WOT\yourname
Meshes should go in Data Files\Meshes\WOT\directory letter.

(See standards page to get the right folders for meshes.
