I have two questions about Gwibber. Firstly, I only have the option of adding Facebook, Twitter and Identi.ca accounts, not Flickr, Digg etc. Is there an option to enable this, or am I doing something wrong?

Secondly, I have three Twitter accounts. I have added two. When I add the third, it gets authorised, but not added to the list of accounts. Any ideas as to how to add a third Twitter account to Gwibber?

Thanks,
xander
