For those who plan to attend there will be a Babylon 5 25TH Anniversary panel at World Con 76 in San Jose. Last I heard the exact date and time are still up in the air due to people creating programming issues. I know the woman running the B5 panel and if you need any info before or after I can get in touch with her to answer your questions.
Also noteworthy is that there will be a Celebration of Harlan Ellison panel at World Con 76 as well. I heard the Celebration panel at SDCC 2018 was really good.
If you attend World Con 76 please let us/me know about your experience.
