Klaus, sorry we don't support syncing with Citadel. I'm not too familiar with Citadel, but if it supports iCalendar, you could subscribe to your RTM tasks in Citadel (for read-only access). More details on iCalendar here. Hope this helps!

Emily,

Thanks for your suggestion. Citadel does support iCalendar and directly stores iCalendar entities as messages in the server. However, Citaldel uses the GroupDAV standard as its transport mechanism, and at the moment I can't quite figure out how to connect RtM and Citadel using GroupDAV. Unfortunately Citadel cannot directly import ICS files.

If I find a solution I'll post it in the “Tips & Tricks” forum.

Cheers,
Klaus
