BPFK (baupla fuzykamni, i.e. "Language Planning Committee", also known as byfy) was a standing committee of LLG with the charge of improving and maintaining formal descriptions of Lojban, elaborating undocumented and under-documented language features, resolving inconsistencies and errors in existing documentation, and responding to issues that arise in usage. Initially chartered in 2003, it was reauthorized by the 2014 meeting of the LLG membership, and presented with a new charter.
During the LLG Members' Meeting of 2018, it was voted to dissolve the BPFK and replace it with a new committee, the LFK (lojbo fuzykamni, i.e. "Lojban Committee"). The LFK is the official successor of the BPFK and is charged with functions largely similar to those of the BPFK.
