[themes] Disabling the "readmore link" to show the complete copy? (sorry second post)

Hello all, Unfortunately I lost all my prior emails and have to ask this question again. I've been struggling with this for the past few hours and am extremely frustrated. How do I disable the "readmore link" to allow a full posting to show and then make the link invisible. I actually made the link invisible, but because of it not being disabled my post also disappeared and I was not able to view it. This is for the front page of a website. All help appreciated, and thanks for your patience. PChuprina
