Thank you, thesanerone. Is this about artist_kaba's post on my website? I've checked others' post on mozilla and google chrome but I didn't see any problem. I don't know why it appears to have some css issues on IE. I am not a coder so I don't know how to fix this. I just hope somebody will find a solution for this or just wait for 3.1 release.
Thank you, mr_green. I did your suggestion. I removed twitter and FB but I don't know how to make it a full page template. There is still space for sidebar widget. I hope I can find Vienna's thread so I can make it totally full page.
