Having looked around the forums it seems that lots of people are getting a blank screen when trying to import CSV files into a mailing list (including myself).
Has anyone actually used this feature successfully? Without it, it kind of makes the whole Newsletter module questionalbe in it's usefullness. I can't see any tickets for it which seems strange given the amount of people who seem to be having the same problem.
I have a client who needs to import/export member lists regularly and so it's quite essential that I find a way to do it, whether that includes the newsletter or not.
Any info or help is much appreciated :)
