Perhaps we should add a note that the "Save Changes" button at the bottom must be clicked for the changes to take effect? We do that in Support, so I suppose some users forget or just don't know?
"You may need to refresh your browser"
I think the user should rather refresh the page, or click the Refresh button in their browser. :)
Also, the correct URL for the Invite page is http://www.livejournal.com/invite/ (notice the trailing slash). I've mentioned this here before, have I?... For those that don't know: I know this is nitpicky, but if this got changed, it'd save LJ some bandwidth, and the users could reach the page quicker. It makes all the more difference for free users who don't have access to the faster servers.
