I am so regretted to sign up to so many sponsors though i have earned the enticing revenue from them. Put the posts ageless in my blog seem a bit irritating and it is totally messed up my blog's initial mission. I know i didn't check the rules properly before i started posting, can blame who, only can blame myself. I know i have to start my own domain asap, and shift my personal posts to my own domain, but i just wonder i have enough time to do this blog migration or not?? I feel sad..
