What lectureships do I attend?

I used to attend several lectureships just to go for the subjects and to hear certain speakers. Then I started speaking on lectureships, and once that started I ceased going to lectureships just as a listener. I had enough invitations that to go to lectureships as a listener only would take me away too much. However, now I am rarely invited to speak anymore, and so I just devote myself to my various works.
