May I suggest clearer wording for the Discussion page, especially important for newcomers, like me.
Calling NABOKOV-L a mailing list is incorrect, even if you used to call it that. Better to call it a 'chat room' or 'communication forum.' Also, your Forum page now has three parts. That should be made clearer. Many words on the page can, and should, be hyperlinked for better navigation. Here is my suggested rewording, with links:
"From 1993 until 2018, the bulk of Nabokov-related scholarly discussion took place on NABOKV-L, our previous online communication forum. Our current website hosts a complete archive of NABOKOV-L here. From 2018 onward, online discussion can be viewed on our site’s three Forum sections. All three sections are are open-access for viewing, but in order to post to them, registration to TheNabokovian.org is required."
P.S. I have similar suggestions for other pages, if interested.
