Mailing ListsFirst, there are now mailing lists (Google Groups) for each. This is something I pressed for since last year, and thankfully now they're enabled and there are good discussions already taking place.
Knowledgebase, Searchable and BrowsableThere is also a new Knowledge Base where they've put many tech notes and answers to questions (other than those already in the FAQs). You can search it via the main support page, indicating which product and type of docs to search (it also searches the Google groups as well).
Finally, I'll share a little hidden gem. If you'd rather not search the KB, you can instead browse it. Here's a URL for each product:
I should note that they don't currently offer these links on the site, and in fact they may change in the future (since they're not published yet), but I don't think they'll mind me sharing it for now.
They're presented in numerical order, which isn't really chronological order, but clearly mixed in are discussions relevant to both old and new releases of the products, to be sure to note that indicator in the info at the bottom of each technote, if you have any question. There's some good stuff in there, and I'll be mining it for tips to share (here or on the mailing lists).
