Most of the time I get IM reminders as expected (I currently have them sent via both g-talk and skype). But sometimes they just don't show up. Usually when this happens I don't get them at all, but sometimes they've arrived the following day.

Like today. I have 4 tasks due today, but I didn't get a reminder at noon like I usually do, on either service. Not a peep.

Although infrequent, this has happened enough times that I'm starting to wonder if I can rely on them.

Any advice? Thanks!
