You got it, all you need to do is dynamically link to SDL (ala .dll) and
then provide the source for SDL (that you use) on your website or
distribution method (CD/Download zip from site) and you will be compliant
with the LGPL. I am unsure as to if linking to libsdl.org is enough, maybe
someone could fill us in on this?

Its a must for LGPL :)

As said in previous post, you could use the SDL logo on the libsdl.org
website.  A good splash logo was talked about along time ago but nobody
ever got round to doing one.  If you do, please submit it :)

Now thats a good idea.  Always support your base :)  Just the website
hosting costs money and we all thank Sam for what he has done so far and
everyone else who has submitted bugs/patches/improvements/documentation.

>Thanks everyone!

Well, we also thank you for supporting SDL.  The more that use SDL, the
more SDL will be used.  The more SDL is used, the better it becomes.

Take care,
