Works for me open mike - maybe someone fixed it.

You can click on your user name in a thread - just like with this link. (I'm absolutely shocked no one else has suggested it!)
You can type a word from the title into the main forum page search box and set the age to whatever. A word often works better for me than trying to remember the whole title.

Prevention of thread loss: you can click on "Add To Tracer" in the dark blue box right above the message reply window. When you want to find it, just go to your personal page and the link will be there.
