I found info and buttons for Fark:
http://www.fark.com/farkit/
I tried to put this into the social bookmark manager:
http://cgi.fark.com/cgi/fark/edit.pl?new_url={URL}&new_comment={TITLE}&new_comm ent={bburl}&linktype=Misc
But this did not work.
I did replace {bburl} by my url, because I am not sure if the bburl code will work here.
Another thing to consider is the linktype. Fark needs the topic of the link to be defined. See:
http://cgi.fark.com/cgi/fark/submit.pl for the link type drop down and the topics you can choose from. I guess it would be best if the link type is not predefined so that the submitter will chose the right one.
