Live synchronization of your CiteULike library to Delicious.com
On your MyCiteULike menu there’s a new item “Delicious Sync” which you can use to set up a live synchronization of your library. Initially this is restricted to “new” YahooID accounts which can be accessed without the need for CiteULike to know your delicious password, but we can do that if there’s demand.
Let us know how you get on and any enhancements you’d like.

(Now it’s working.)
Thanks for setting this up. I’m excited to experiment with it.
It might be cool to have two-way synchronization, so that, for example, firefox del.icio.us extension could work as an interface to citeulike. You’d want to be able to specify a tag which identifies the del.icio.us bookmarks to add to citeulike.
I synced my citeulike with Delicious one time in march 2010 and then I tried many times without effects.
