Piano World requires your actual birthdate to post anything. My insurance companies and 401k managers use my birthdate as a key identifier for password change; it is not information I am going to give away. There are a lot more posters on Piano World, including some techs that will answer every question with the answer "you should hire a qualified piano technician". I do my own piano work, considering that an excellent console now can be had for $150 it doesn't make sense at my income level to hire a technician anymore. If I can rebuild engines, rear axles, automatic transmissions, car radios and stereo amplifiers, I think I should be coached through fixing my own piano without serving a 3 year apprenticeship. The certified piano technicians have a different opinion. I'll figure it out without their help.
