How to make customized theme available to the community? So far the "search" function is only addressing theme maker and not the theme name. Is there any way to improve that?

Administrators, it should fit in your strategy of making a facebook.chess.com site alike!

go here: http://www.chess.com/home/themes.html# and click on 'create a new theme'. save it, and then you are all set.  it's fun to experiment with.  :)

The prob is that the search function addresses the creator of the theme(s) (username) and not the theme name itself. Then, how to search??

Yea, search by the theme creator name.  If you type skwerly into the search, my theme will come up.
