Oh, tag subscriptions sound like fun. People could subscribe to their usernames, and it would emulate a feature I really like on another forum, mention notification. And no one would have to type an @ in front of the name to make it work.
I'm not entirely understanding this idea. Could you elaborate a little?
Okay, in some forums I could write @Micheal Tanczos in my post and the forum software would process that as a "mention" and you would get a notification that you had been mentioned, and clicking the notification would take you to my post. The problem with that is the @, because people who don't know about it don't use it. Probably the confusing part is that I was assuming that any tag term people had subscribed to would be added to an auto-tagging feature. Example, if I subscribe to "sunsndshadow" then when a new post is made it would be searched for all subscribed tags and if "sunandshadow" was found in the post, it would be added to the post's tags. Or this kind of thing could be done while typing, like Facebook recognized when you start to type someone's username and offers to autocomplete with a link to that person. If there isn't any auto-tagging then subscribing to one's username could work as a direct substitute for mentions, but isn't an improvement on it, because the post writer would still have to specifically tag me.
