Just chiming in here as well. (I had submitted a ticket and was directed here.) For me, the loss of data was a big deal, since I had one post in particular that represented years of information. Luckily, Google had a cache of it.
Short of having the forums back, being able to create a secondary Page within the add-on would be ideal. This is for a very long FAQ that my add-on Rarity needs. I don't want to put all the info on the main add-on page, but for now I think that's my only solution.
