Ugh. You don't need an MIT-level script to use the search engine. Is that really what you kids think?
Edit: Response to below, since the kid clearly does NOT understand this.
To find the last time someone posted, click
Search in the top right. Type in the user's name in the "Filter by Member Name" box. Under "Result Type" click "Show results as posts". It will show the first 1000 of that user's posts, from most recent to least. The top post is their last post. Does exactly what you're saying, without any script, let alone whatever misconceptions you have about college being true. (Seriously, look at
this. They're common, and easy to make.)
Even quicker, if you're just looking for all posts by a user, click their name to see their profile, click "Profile options" then "Show user's posts."
