From the website:
The motu proprio has been released! The next step is to start putting the Catholic faithful who want to assist at the extraordinary form of the Holy Mass in touch with Catholic priests who want to say the extraordinary form of the Holy Mass. Please fill out the form below with your contact information so we can help you make a connection.
Please make sure to include your geographical information (it will be difficult to link you up with others in your area if you don't), as well as an email address so that you can be contacted when a match is found. Your information is private and will not be shared with anyone without your consent. Also, including your parish of registry will be very important for helping to connect people in the same parish who may be unaware of each other.
