Minimalist - A Simple, Clean, Yet Functional theme for Vanilla 2.0
This is actually my first Vanilla theme i've ever created so go easy on me :) Originally created as a learning experience so i could attempt to develop themes for hardWIRED (Mine and a friend's site) to take the stress off my friend so he can concentrate on developing his Custom wiki for Garden. Thoughts & Opinions much appreciated, As it will influence any future revisions :)
Fully skinned by the way as well no header change and release :P As much as i could find was skinned, with a few custom additions.
Sorry for the low quality screenshot, No idea what happened there
