As mentioned by some other here, you could indeed create basic support via the use of pages if needed. I have even seen some people who have just used forums for this purpose, by creating a forum where members can see only their own topics.
We certainly appreciate that some users will miss the features than this offered, of course. And we will try and point people in the right direction where we can. If you have anything further to add regarding the deprecation of this (or indeed any other item), please feel free to discuss in the topic provided here. You will see this has however been discussed quite at length.
