I made a simple banner for my site quite simply. I googled 'free logo creator' and played about for a little bit. I finally got one that I like the look of untill somthing better comes along.

To put it on you're forum, it is best to first save it to a location on you're computer then go into you're admin panel > styles > modify the picture > banner and upload it from you're computer.

I found out how to do this myself, so no doubt someone will come along and tell you an easier way of doing it!!!
