I think this is good that you choose for each topic a new thread. When one can sum it up under one topic then write it under one thread. This makes it much easier to find old threads (as the search-option is not very good here).
I support the colour/outlooking idea very much! This could be organized with different templates to choose. And to add some chess fonts could also make the site a bit richer (and slower?).
But you can also play under www.chessatwork.com and other mirror sites and so you have differnet layouts availible!
The idea with the nb of currents games in the "Your status" of MyHome is good!
