how the "watch" function in Java developer's forum used

I post a question weeks ago and I didn't expect that people keep on updating the answer times again. And the answers are really incisive.
See for example:
http://forum.java.sun.com/thread.jspa?threadID=5216558

I get noticed by email of their answer because I add this topic to my "watch" list on Sun't forum and select email update. That's really a good way to get informed coz you don't need to wait on-line for the answer.

I also use the Google compt.lang.java.GUI discussion group. These are the two I stick to.

So my conclusion on using forum for Java problem is:
If you don't want to spend time on your post format and hope to get a quick answer but may not be correct, use the Google group.
If you a not in a hurry, describe your problem in detail, give a "Short, Self Contained, Compilable and Executable, Example Program "(SSCCE) and wait for sure the answer from the Java forum.
