[Please Delete] Unified topics from all forums link

[Earthk]

I've just started 5 forums and I want to supply a link where all topics
of the forums are combined. I know I can do this by going to search and
putting a * at the top field and enter. But I don't want my visitors to be
doing that all the time. Is there a way to provide a link which gives the
same result? I guess the link will have to use search.php?
