FYI this has now changed to "April", according to a recent reddit post.
No, it has not been changed. The community member who posted that wrote "Alt.Market
is currently being tested by community members and is slated to be
available to the general public by April. Some screenshots have leaked to Slack/Discord members and there is a lot of buzz about how sveldt and intuitive the interface is"
So in other words people are already using it (not you) and it will be available -- by -- April. Which obviously would mean in March.

It's cute how closely you pay attention to what's going on, but then try to act all dismissive of it.
