Moodle failed my trust

I read today this blogpost about author's experience with "overwhelming" teachers with Moodle rich features on the training, on the presentations, just to confuse or even scare them..

I found I am guilty with that too ;-).

But another idea crossed my mind. Did you ever "hype" some Moodle feature that didn't work as you expected later? Did you say to yourself: "Oh man, I wish I have never installed this, I wish I have never spoken about that, this is so much pain in ...". Did you ever regret you went with Moodle?

This article is not about blaming Moodle, unfortunate events happen all the time everywhere. I am just interested in situations, features that didn't go well or as you planned and how did you solve that? I love happy endings ;-).

I am looking forward to your comments :-).
