Updates from Formumotion has allowed for a basic tagging functionality. When you type @, followed by a person's username, anybody reading the post can hover their cursor over it and get basic information about the user. It doesn't look like this tagging feature triggers a notification. Also, a function has been around a while now that allows for a thread to be marked as "Solved". You'll have to edit the post. it's one of the options under the text field.
Old Updates That Never Got Published:
-Polls section forum description modified.
-Small ranking glitch fixed
-Some post count requirements for a few top ranks have been changed.
