The BALUG-Talk list migration did go quite smoothly. Still need to migrate the list archives, but will get to that.
A couple other bits one might want to be aware of on the new hosting:
Also note, with the new infrastructure, notably anti-spam measures and greylisting, postings to the list may not appear quite immediately - especially if one hasn't posted to the list before or in some fair while (or notably from the same SMTP sending IP address before). So one may see an initial delay of a couple minutes up to about five minutes or so (depending upon one's sending MTA) or more.
Also, while the site will generally be up, available, and on-line, it's not exactly a high-availability infrastructure - so if at any point it appears to not be available, rest assured we'll take care of it (and any postings sent earlier, will still generally still make it - may just take a bit longer in such circumstances).
