I missed this feature when we left vB and was so happy to learn of this add-on. It is so nice to be able to realize 'who' will be notified of an update to a particular thread, plus it affords me the capability to give some users a heads-up about a thread if I think they may be interested in following it.
1.2 update was a good update. Better placement for the container and icon now consistent with other thread alerts. Excellent job yet again and shows the improvements chris strives to make and happily doing so. :)
