How can i craete/apply a new unit texture?

Ah, I think you're talking about the MipMaps. Yes, they are used at different distances, but you don't want to display them when you're editing the model. When you save it, ensure you generate the MipMaps as well - as it says in the guide I linked to above - they'll be automatically created from the larger version you edited.

thanks to u one more time,
it seems to me i got it. i finished some kinda heavy armored hoplite but haven't tested it yet in game as i'm still not getting through those complex skinning guides... hm anyway i would like to post some image of my "work" but i'm not getting how to do so. what do i need to type in the "insert image" URI?

You need to host the image somewhere on the net, such as imageshack, then you put the link to the image in [IMG] tags so, for example:
remove *
