Adding Static Text to End of Posts

Hello –

A forum search is failing me on this one . .

I want to add a line of text to the end of every post on the main index and individual post pages. This text needs to be part of the post content and appear above the SexyBookmarks plugin.

I went with the SexyBookmarks plugin because I liked that it gave the ability to populate Twitter text. However, when I used it in manual mode to make it look the way I wanted (with “Share This Post” text above the icons), the pre-populated text went awry. I went back to placing it at the bottom of all my posts and index page, and that made the pre-populated text appear the right way, but now I can’t figure out how to add text that reads “Share This Post” at the end of all my single posts and on the index page. I tried adding it in the loop within the the post content div, but the share icons are appearing above it.

I know there’s a few plugins out there, but they’re all out of date and don’t work the way I want them to.

My site’s not live so I can’t provide a link. I’m using a TwentyTen child theme.
