LiquidThreads/Implementation

LiquidThreads is implemented as a Mediawiki extension. WikiEducator is currently using version 1.2, at least in part because upgrade to version 2.0 appears to fail for some threads.

mw_historical_thread
Note many hthreads can share an id, which is the same as the id of the live thread. It is only the id/revision combo which must be unique.

mw_user_newtalk
Standard Mediawiki table.
