How do i use the search forums on google.com for example trying to find i am legend.

Might want to put this in Questions, Feedback, Assistance, not sure if I should answer your question, might negatively reinforce this tendency.

(Advanced Search in top right, Search for Keywords box, type in "I am Legend", change Search Entire posts to Search Titles only, and you should be good to go.)

for search with google (much better for search forum option), use follow:

site:forums.ffshrine.org [search words]

i using many, and working very much :D
