Tres'ni uploaded TCL4BB sources to GitHub for this site and now Mojmir will start working on it, so this very unique plugin can be used in a 64-bit Blackbox environment.
Tres'ni worked on TCL for a number of years and his efforts are invaluable. Though he has stopped using Blackbox himself, he is still one of the major figureheads of the community and he never stopped caring for it. Thank you, Brian!
