I find it a bit odd to discover that you have made a theme available that can't be made to work properly since you don't offer the necessary options.
The theme Arras (now available for blogs hosted at wordpress.com) looks very odd since it leaves huge chunks completely emtpy where thumbnails are supposed to be shown. The thumbnails require "custom fields", something that is for some reason not included at wordpress.com
Is this an oversight, that you approved this theme for use at wordpress.com even though it can never work at wordpress.com as it is supposed to be?
For example, see my http://starcastlehoundsupdates.wordpress.com/ and compare it with what it should look like
http://www.arrastheme.com/
The blog I need help with is starcastlehoundsupdates.wordpress.com.
