Welcome to OCF. The posters here are generous with their knowledge, so bring on any questions you may have.
In the search box in the upper right of each message-board page, type
photodynamic and hit the Go button. You'll get three pages of results, including two
substantial threads. A followup to the first thread is
here.
These threads were started by people who have had PDT. Click on their names to get their profiles -- you could send them an e-mail or a private message for additional details.
More links about PDT are available
here and
here.
There is a separate search function for the main part of the OCF site. Click the gold "search" link at the bottom of each message-board page to get to that search engine.
