This forum seems great, and my first order of business is to show off my world: http://i.imgur.com/DgCoFXi.png

I made it by scribbling three or four blobs onto some paper. From there, I scanned it into my computer and traced what I drew with MS Paint or something. I then added more islands and started filling it in with color. After that, I threw in some lakes and rivers. After that was all done though, I had to go into GIMP and soften up the edges of the islands, with the blur tool... and VOILA!

What do you think, I know it's not the best and it's missing quite a few elements, so feel free to criticize!
