Hi,

I have a website that contains some articles on seed germination. Visitors
can suggest articles to add and review the articles on the site. The site
itself is part of a commercial site, but this part of the site is really
designed to allow visitors to learn something. The site also contains a
calculator to let visitors figure out the cost of the electricity they spend
on their plants.
