Just setting up.

So I have been playing on Second Life for a few months now. I am learning a ton. I have a fair grasp of the prims now, though still learning some of the subtler tricks of prim torturing. I am starting to get a descent grasp of the scripting language and am having a lot of fun creating and decorating scenes. I need a space wehre I can keep track of a few of the things I am learning along the way.

In particular this morning I was wondering....does someone have a good low down on the various permissions options and how they all interact. I mean, yes, I understand the basics of copy/mod/transfer, however, I am interested in the more subtle nuansces of complex objects, like an object that has multiple parts and scripts and contents.

Sometimes, you have an object that you res, the original stays in your inventory but when you go to delete the ressed object you get a warning that there are 'no copy' items inside it.

Sometimes, an object shows as no copy/no mod in your inventory and yet that is just because of one script in the object and really you can manipulate the object quite freely.

What about an object with a no mod texture?

These are some of the questions I want to sort out for myself through reading and experimentation.
