I've also taken the opportunity to correct the grammar on the name of the link. Sometimes it's the little things.
Do you mean that the current link "Topics I have posted in" should be called "Topics in which I have posted"?
BTW Google is your friend!

Nice, that works quite well as a stop-gap. It's not 100% perfect (sometimes it picks my handle up from a cached version of the "Most Recent Topics" panel on the right for threads I haven't posted in) but it's pretty good. Thanks.
+1 to the original post. It's there in every forum I've seen so far.
