[Remind-Fans] "Sticky Notes" for "remind"

[LarryD]

Does anyone have experience with "Sticky Notes" applications, especially 
those used with "remind"? I know there are many, but I don't know which 
are better than others.

My problem is that I need some events to be "sticky". That is, I need 
some events to be visible and ONLY disappear after being acknowledged. I 
missed a payment because the announcement disappeared and I forgot to 
pay it. Not good.

Can anyone help?
