Memberships for the PDA are free and will remain so for the time being.
If you'd like to sign on, please simply join the PDA 'Discussion Group'
by clicking the link above.

In the future, various memberships may be offered at differing rates,
such as 'Individual', 'Family', 'Corporate', etc.

In the meantime, let's leave it for discussion and build an association
with something valuable to offer.

Thank you,  -Tom
