I did try to have a Wordpress - based blog late last year but I never really master the environment since I am all used to Blogger's more user-friendly framework.
This got me all confused since some of my blogger-friends have EC widget on their Wordpress blogs which led me to write support tickets to both Entrecard and Wordpress. Wordpress tech support however pointed out that scripts are not allowed. SIgh!
But, I wont give up though because if other WP blogs work ok with EC codes, then, eventually my blog will be up and running with it also. I just have to look for ways to remedy this problem. Hmnnn! I wont be a techie teacher for nothing. hahahhahah!
