I'm one of those poor souls having to deal with Lotus Notes at work.
Well, actually my soul is kidnapped in Hell and I'm forced to work with the damn tool for repentance. Words are not enough to describe the unbearable agony that the super fat Lotus Notes native client and the funtastic iNotes web interface bring to my life. I started thinking we do this for charity towards the Notes sysadmins.
Having said that, I need Sametime, and meanwhile has a few bugs open upstream in Empathy, one of which is the missing field to specify which server to connect to (!!) in the account settings.
If there's nobody else who wants to step in, I would like to be the mantainer; any help from co-mantainers is much welcome.
