Does Diana Muldaur who played the 2nd doctor in the 2nd season ever go to Star Trek conventions?

Muldaur was not retired at the time she joined the TNG cast — she'd just finished appearing on the drama series A Year in the Life, and moved on to L.A. Law after TNG — and she was 50, only two years older than Patrick Stewart was at the time.

There is actually a video interview where she said she was getting ready to retire when she got the call for TNG. Very well documented.
