PGreen is a 2 column widget ready wordpress theme just right for your family friendly blog. If you look closely at the design, you would find that the theme lacks real header. The so called header which is present in the design is part of the content.
You have the option of changing whole of sidebar as this theme is widget ready. The search function is kept out of widget as its position on the theme is supposed to be the best. The design has a clean archive page for category posts and past posts with respect to date. There is also a separate search page. However, this is an extra page as search results could also be handled by archive.php.
Below title you could find post date and there is a bar in the bottom which contains comments, post categories and edit link. Admin could see that when he is logged in.
Go ahead and download the theme and remember to pen down your feedbacks/problems. You could make my day with few lines of praise or you could even shout at me loudly.
