jbovlaste is a dictionary editing interface by Jay Kominek, massively updated by Robin Lee Powell, now in full production.

Brammo also created a program to create a dict database out of a database generated by jbovlaste, lojtexdict. "Dict" in that sentence is not an abbreviation but connotes a type of software which creates "dict databases." Using this download involves prerequisites of a technical nature.
A local Tiki hack has been made to allow Tiki to work as a wiki for semantic lists of jbovlaste words; see jbovlaste Wiki Local Tiki Hack for more details.
For editors: this list tells which useful English words are yet to get a search hit in jbovlaste. The sooner the dictionary covers these words, the sooner it becomes more useful at least for English speakers.
