Anne,
At the bottom of the newsletter, the words 'All Things Plants' are in blue and this is a live link.
If you click the Forums tab across the top and in the banner, you'll see all the forums listed in alphabetical order and grouped by topic.
And with the new system, when you enter a thread you've clicked to watch, it will automatically take you to the newest post. I think if you are entering a new thread and find you want to jump ahead, you can click to the page you want to jump to.
If you click 'Watch' on any forum, that forum automatically shows at the top of your page.
Does this help, or did I misread what you were asking?
