Question on layout creation re: ethics?

[Rhaethe]

So, here's my question.

I'd like to work on creating a layout that is similar to the EQ2 UI frame setup (or Oblivion .. I've not decided). Now, I know, when it comes to code, I am far more efficient at adapting already existing code, as opposed to creating fresh new stuffs out of my head.

That being said, I would assume I would need to find a layout that would suit my purposes, and then ask the author if I could adapt their code for my use? And then, if they say "ok", my next question would be concerning the EQ2 (or Oblivion) unit frame graphics ... if I could figure out a way to mimic them, would that infringe upon anything?

This is somewhat I long term project for me, and I'd like to make sure all my ethical ducks were in a row before I start
