Hi, I'm new here and I can't find your search option beside the Google search. Help?
In Google, you can search for
site:budgetlightforum.com 18650
if you're looking for 18650 information, for example.
If that's isn't good enough, you're probably out of luck, unless you want to search for something in a specific thread.
Good tip. Thanks mate. 
There is a Google powered search box in the upper left hand corner of every page on BLF. It has always worked very well for me.
