f you still want to have the link directory on one page - that's possible as well. Please create a new link directory in Preferences -> Link Directory settings -> Link Directory templates. Select "plain", not "tree-like" and on the following step put a check "split into pages" and enter some huge number that you are not planning to exceed

Say, 10.000. Finish creating the directory and preview it - it will all be on one page. After that yo can put the link submission form above the links - locate it between the code
Code:
<[!-- Links exchange invitation - Start --/]>
<[!-- Links exchange invitation - End --/]>
And cut/paste to the top of the body text.
Saving the directory locally as HTML will let you open the HTML file and extract the code between the <body> </body> tags to paste it to your CMS
