On the main/news page, there is a link near the top in a red announcement block for the
WotC Druid article playtest.
1) Would you consider marking (or adding text in the description) that says its for a
DDI subscription?
2) You may want to consider changing it to say "preview" since
WotC changed what they are calling it to just be a "preview" (rather than "playtest" for feedback as they don't have time to make adjustments prior to the book going to press).
Not a huge deal, just something I ran across while looking at the news page.
.... of course, in about 5 days, you'll have the exact same thing for the new Invoker class (preview of the new divine controller class that introduces summoning to
4e)
