Allow facebook access "forever" + repost items?

Hi there,

I just want to ask, why the dopplr facebook widget does not have an option to post to my profile?
Of course it is great, that it is posted on facebook, when I go on a trip, but I'd like to post it both when creating the trip and also when actually going there (or deleting one, lifestream-like).
Also a "post two / [x] weeks before going on trips" would be a cool option, so my facebook friends would be notified in a timely manner! :-)
(I have to add, they are all not so much into web2.0 or/and sharing, so they just aren't signing up for dopplr, although I invited them.)

Thanks for your help in advance.

Kind regards.

PS: Oh crap, now I saw the other thread. It seems posting was deactivated, but I never deactivated it!!! How could that happen? And can I "repost" my not published items?
