Question about robots.txt file

It is blank

[iGLOBAL NiCK]

I have a blank robots.txt file, and I was wondering what I need to put in there to allow all bots and spiders to crawl around on all the pages, or should I just leave it how it is, blank?

In my meta tags I have the line:
<META name="robots" content="index,follow"> but I also want to make sure in the robots.txt file that I allow them to crawl around.

Thanks for your help.

For he robots.txt the entries you add are to dissalow access, if it is blank it will not effect spidering. The bots will see this as "no restrictions"

A lot of people place a blank robots.txt file to eliminate 404 issues when bots request the non existant file.
