The general rule is to never ask for updates unless really necessary. Devs typically give updates when they feel like it. Anytime spent replying to you is time that could be used for development, or beer.
Meanwhile, stalk them on github, twitter, or whichever way they can be found. But do so silently and don't creep them out.
The reason we set up the technical subforum is so we keep this development subforum actually for development. We will try to be more strict in this area with regards to what type of posts and questions are allowed there.
This thread dump is for all such posts, to enhance the experience of the development subforum
