Ana - If you like I will set up a page entitled "Gardens with Crotons," "Landscaping Ideas With Crotons," or something along those lines. Let me know what you would like. I can place it on the Main Croton Page where the links to the CrotonPedia are. I can then place a link to the Codiaeum Connection there as well and make it the entry page for the entire Croton Experience with a more noticeable link to the Forum as well.
Something I've been meaning to mention ----- now that I have been doing a lot of research and code manipulation to optimize our Search Engine results, I noticed our Category Pages (Narrow Leaf, Alphabetical, etc.) only have the word Croton once - and the pages of the Crotons (like Magnificant, Alley Cat, Daisy, etc.) don't even have the word Croton or Codiaeum on them at all. This means that the Search Engines have no idea what they are a page of. So we are missing out, and need to do a better job of getting the words "Croton" and 'Codiaeum" on those (and all) pages as much and as often as possible. The first sentence on each page is especially important for search engines when determining the content of the page and to rank it in their results.
For example, for our palm pages I am converting every first sentence to say something like - "Dypsis decipiens is a large cold and drought tolerant palm from the high plateau of Madagascar." Then the search engine has some pertinent information to work with. If someone searches for "drought tolerant palm," "Madagascar palms," "cold tolerant palm," "Dypsis," etc. then this page will be recommended, based on that important first sentence. Just something to think about, as I know you mentioned our rankings before.
