Block doesn't show in Foliage/D6

Have you enabled the block to be shown for appropriate content types? By default, the block will not appear for any node -- only those whose content types you've specified.

From the installation instructions on the module's project page:

You will also need to tell the module the content types for which it should display the block. (By default, it only displays for the content type "Story.") To add or remove content types that display the block, go to Admin > Site configuration > About This Node. Simply check off the content types you want.

(Edit: Copied wrong graf from project page. It's been corrected.)

Thanks for the kind words. I'm closing this issue.
