Ceejay, she being my other half, has relaunched her website to provide HTML templates. It's possible that as new templates are released that we'll also convert them to Serendipity but she doesn't have much Serendipity coding experience, and might need some help from other Serendipity users as time goes by.
Anyway, getting back to Ceejay, she's got a new masthead on our old Christmas2006 template and she'd be happy to read your comments and thoughts, especially to those of you who've been kind enough to pass on your best wishes in the past.
