I'm just waiting for my last shipment of plants to come in, then I think I might start a journal, too. And it's good to know that they won't dig up the dirt, I'll definitely have to keep that idea on the table. Thanks for sharing the photo! My tank needs more plants that my goldfish can eat. I'd love for my eventual upgrade tank be half goldfish salad bar.
As for the signature, you type whatever text you want the link to say, then highlight the text, then click on the 'insert link' icon and put in the address. Took me a minute to remember how I did it.
