I just fully noticed that welcome messages are not being sent to new users (for at least a week, probably longer) despite them being sent in the past (there have been no changes to the MediaWiki pages controlling welcomes). I believe the problem may be AWB's checkpage (a message was sent after the checkpage was created) so my questions are does the bot for welcomes use AWB and, if it does, which one is it now? I just added WikiaBot (though there's Wikia too) to the list and I want to make sure I'm correct.
