The new membership form is posted in the Forms area:
main.uschess.org/component/optio … temid,412/
See: main.uschess.org/docs/forms/Memb … 2-5-08.pdf
As I understand it, there is just one general membership form being posted, for use by members as well as by affiliates and TDs. There will be other forms for any membership types not shown on this form.
