Search is so-so, but it's there for you to find things. We use Google search, so their hints will work here.
The "Active Threads" on the left menu shows you threads since you've last logged in. You can also use the "Recent Posts" above to see various searches in the forums.
Questions of the day are linked from the front page and you can filter them.
The articles use tags, so if an article is in "Administration" and "T-SQL", you can find it by choosing either category in the Articles section.
