We use Liquid Threads here for discussion. It is no longer maintained. I am exploring the possibility to move to Flow, which is still maintained. But it won't be easy and migration is likely to be disruptive to some extend so it is not going to happen very soon.
Note: I vote strongly support to migration, because since October, nearly all of my actions are stucked by a huge, huge and huge number of CSRF token errors. Do not say some "wrong from HHVM", HHVM doesn't result any wrong, the only wrong is from LQT which is too hard to uninstall.
