May I use your stuffs?
Sorry, but it doesn't work that way. You cannot just ask "may I use your stuff?" and take whatever you want. We'll never agree to such request. If you want to use some particular models/textures or something, send a message to the author of that thing (see brf names - "bart_xxxxx.brf" is for B@rtu$, "dedal__xxxxx.brf" for me, "tul_xxxxx.brf" for Tul... other stuff is either 3rd party or not available to share anymore) explaining what exactly do you need.
Also, if you have your own project, it's good to show what already have yo done by yourself, since we all are much more willing to share with people, whom we see that really put their heart into theirs mod.
