Guidelines for Link Exchange posts:
1) Be specific in your subject line so that people may scan the category for link exchanges that might interest them.
2) Post the link to the page that you need links for along with the preferred anchor text and description. (do not post "please link to my site") Include any other details that you think may be useful to people who may want to link to you.
3) Give details about the types of links that you might be willing to give in return. If you only link out to certain types of sites (or pages on certain topics) then be sure to include that in your post.
