Can anyone suggest a skin for a poetry critique board? Is a skin to replace the color?

Is a skin to replace the color?Generally, a skin involves more than just replacing colors. It usually includes reworking the layout of the pages (by editing the templates) and replacing buttons and other images.

If you want to change the colors, you can do that fairly easily (and safely) from main CSS area for the style in the admin control panel. You cannot break the forum if you only change the colors.

I don't know of any skin that would be especially appropriate for a poetry forum, but if you look through the stuff offered here, you might find something you like.
