Hi, I have seen on other forums a notification that comes up when someone has been quoted in a post. I find this feature very helpful because if someone quotes you in a post and asks a question related to content, you get notified when you login and you can go to that post to read and reply. I think that helps a great deal especially when someone needs assistance with something that was posted by someone else. I know that it can be done via PM as well, but that is not beneficial to everyone else who may benefit from the same question and answer. I think it would be a very nice feature to add to the forum. I see that there is a plugin here but I am not sure if it is compatible with mu-43 vBulletin version since the plugin was last updated in 2010. Maybe there are other options as well? Thanks.
