Thank you so much, helped me loads  ^^

I know this is probably pretty basic for you guys, but i've had a look around and i cant see the answers to these questions i have, and help would be really appreciated (its not modeling or vertex related) ,well a wee bit. The could also be useful for amateur like me who have no idea how this all works.

1) Whats the difference with the seperate import section in the brawl vault and clicking one of the characters
2) am i correct in thinking that for mods under specific characters, textures act as another costume , models replace the characters, (what do modeltextures do , just replace and add costumes?)
3) am i also correct in thinking when you download a model for a specific character, its moveset stays the same unless a seperate one has been made.
4) see the cs for giga bowser and wario man, can u replace them with a totally different character
5) what does it mean to keep a character on a port.
6) Also when does it mean when a character takes up a 'slot'
7) After adding mods and stuff to the wii will i be able to restore the game to its origional default ssbb .

I cant remember if this was everything. Really sorry to ask so many questions ( theres plenty of guides on how to install these this , but i was unsure of basically the effects of doing these things)
