cant figure out how to do a search on this site?????

Do this...
1) locate the band near the top of this web page... [it reads from left to right, Home / Explore / Latest / Popular / and so on]
2) click on the word 'Explore'... a menu of 7 items will drop down under the word Explore... the last word showing may be 'Tags'
3) go to the empty white column on the far right side of the drop-down menu
4) in that seemingly empty white column on the right hand side of the drop-down menu, use your keyboard to attempt to scroll down as if there was a location indicator in that white column
5) as you move the 'invisible' indicator down in the blank white column, the menu will scroll to expose the word 'Search' below the word 'Tag'
6) click on the word 'Search' and the Search Forums menu will be displayed.

You're not the 1st person to have difficulty with locating the Forum Search Function.  This is one (1) of the idiosyncrasy that was incorporated by the software developer so that only serious readers can access the treasure trove of information in the archives of this web site.  There are other quirks, so don't hesitate to write when something seems frustrating.

Hope this helps.
