With MysticBB you can also make a New Scan Search, to show all topics/posts,
created after your last visit or a date you can set.

While logged into the forum, you can immediate press N and see all new topics
and posts, after your last visit to the BBS. 

Press D to set a new scan date. The default value is your last visit day.
Change it to whatever you want and it will show you all the topics created
after that date.

Simple... :)
