If you put different names in the subject line instead of RE: *Insert topic name here*, it'll show up as the most recent reply. Take my subject line for example. Now, if you go back to Home, it'll say I replied to 'This is a subject line'. I'll stop that, but it's not just me, you know. I actually got the idea from someone else doing it. I also didn't say anything about dancing bananas in that column- I was the corn guy.
Btw, I'll change my avatar then. :(
