Subscribing to forum topics without replying

How do I subscribe to an individual topic in the forum without replying to that topic? The FAQ says

“To subscribe to a topic, reply to the topic with the subscribe checkbox checked or click the “Subscribe topic” link within the topic itself.”

…and I can’t see such a link. Is it there? Am I blind?

Set the board style to “prosilver”.

User control panel > Board Preferences > Edit global settings > My board style > prosilver

The other style (DEVONtech) does not show the “Subscribe Topic” link.

How strange, but at least I’m not selectively blind. Thanks korm.
