Apercevoir/s’apercevoir:  to glimpse, to see, to take note of

All mean more or less the same in English. Are they interchangeable in French or are there subtle differences?

Are croire à and croire en interchangeable? If not, what is the difference?

Is there any difference between the two ? or is se retrouver to meet someone which is prearranged and rencontrer more random? I've noticed that kwizik seems to favour se retrouver as the best answer

thanks
