Topic: Licensing - what does this mean?

Hi guys, I'm working on a freelance application for a client - its a simple News based website and alos has a blog built in. I wanna use a few freely available scripts such as http://www.fckeditor.net and stuff from the www.dhtmlgoodies.com website except I'm having a hard time figuring out the licensing GNU, LGPL - all this legal talk freaks me out and I don't want to get into any trouble here. So all these licences - does it mean I can use these libraries in a website I'm building for a client? Or are there any hidden strings attached?

Like anyone has a simple watered down easy to digest written transliteration of these licences? Sorry about the question - I've been working alot and my mind hasnt been its usual wrecked self :-S

It all depends. Visit opensource.org for details.
Generally, if you're running the website as a service (ie. you don't hand out source or binary for the website), even GPL
is usable (might have changed in the GPL 3.0).

Under the GPL, you hand the client the (binary) website, you have to hand him the code as well, and he's bound to do
the same with everybody he hands the website to.

Wikipedia has a nice table: http://en.wikipedia.org/wiki/Comparison_of_free_software_licences
