Why Google still not yet cache my site?

[webdesign]

Hello everyone,

I've made SEO do-follow forum http://www.seoerforum.com since 2 days ago and it got indexed pages when I search sites on google with command : site:www.seoerforum.com but when I search with cache google command, It didn't show cache page of it on Google.

What should I do now for Google cache my site quickly ?

Please share any tips
