Not sure if this is the right topic area to post this, but here we go.

I was wanting to do some whois querying in a sketch, and not finding anything for Processing, found this http://www.skytouch.com/soft/java/whois.html which, with a little bit of tinkering, was able to get running in Processing.  

Now, I was thinking that this bit of code is kind of handy, and that I would post it to the board.  But, for the most part, it's the other guy's code, with some slight alterations by yours truly.  It's released under a GNU license, so I am thinking that it's ok, but I wanted to see what the community thought.  

This is my first time dealing with this sort of issue, so I wanted to see what the protocol for this is.  My inclination is to post it with credit and under the GNU license (since that's what it was originally), but I am not sure about the ethics of this, and how much change to code warrants credit, and so on and so forth.

Thanks in advance.

Thanks for the quick reply.  

I had read that, but since this is my first time doing this (just modifying someone else's code, and releasing it) I wanted to make sure that I was doing the right thing.  To be honest, the legal speak (even though it is in pretty plain english for a legal doc) made me nervous, and I just wanted to check.

Thanks again!

Will do.
