I opened up a Wordpress account and tried to post code in for a link back to my website and when I was finished you can still see the code there, I was trying to make a link that clicked through. If Wordpress will not take HTML for a clickable link then how can people use Adsense on it? Please write back with a solution.
far as im aware you can put your own adsense on wordpress anyhow. about html tho, try going into admin > users > your profile and un-checking the ush rich text editor bit
