1. Put it as a sentence the FAQ 137.
2. Modify FAQ 195:
Title: Can I copy or syndicate my entries from another journaling site to my LiveJournal?
There also is no way for entries that have been downloaded from another LiveJournal or from a journal on another site to be uploaded to a LiveJournal.
The only way to add an external entry to your LiveJournal is to copy and paste the entry's text into the Update Journal page. When doing this, you can set the appropriate date and time for the entry by changing the values in the "Date" fields on the Update page. Adding an entry in this way will cause it to appear in your journal as though it were originally posted there on the date you specified. If you choose to do this, you may need to enable the "Date Out of Order" option; this will also prevent your friends' Friends pages from being flooded with the new entries.
If you add external entries to your journal using this method, there is no way for comments posted on another site to be added to this entry for you. You can, however, include a link to the original entry and its comments on the external site in the update.
If you want to use the above method to copy a large number of entries from another journal to your LiveJournal, you may wish to use a downloadable client to add the individual entries to your journal, which would eliminate the wait for pages to load.
