All the manual alphabets (called “fingeralphabets” here) that are labeled “Work in Progress” have been begun but are not yet completet.
Sometimes, all that is missing is an approval from an official party. Sometimes I have still to sort through contradictory material to find the correct signs of a specific alphabet.
If you can offer help in form of contacts (preferably someone who speaks English/German/Portuguese/Spanish/French/Italian), please contact me for further information. Your help would be very much appreciated.
