I think it's a matter of proportionality. Usually an off topic post has a life span of a dozen messages or less so who cares. If it becomes a hundred messages then perhaps you need to rethink, but for a dozen messages who cares. You might institute a convention of listing [OT] before you post something about Xylo and that way people could filter the contents. You could discuss this posting convention on the page that happens before entry to the list.
What I would like most to see is some way to index and search the titles and text and authors of the messages from the website. I'm forever remembering some snippet I read on the list that I would like to review, but I don't have a clue what title or even what month that messages was posted under. I read this list from several computers and downloading a file and indexing it myself would be cumbersome. For a slow list that solution might work, but for a list with the volume of postings this list has it would be very hard to keep current across several computers at widely disparate locations. 73 Lee W9OY __________________________________________________ Do You Yahoo!?
