How in this forum can I get a list of all the forum threads that I have contributed to, or all the forum messages (not inter-user messages) which I have posted (including forum messages that I have already read)? In Renderosity I can call an ordinary search-for-text with no search string and my username in the search-for-user box, but when I try that here I merely get a complaint in red that I have not supplied a search string.
Go in your forum user profile and look at the left side. You can see all of your posts there.
