hiiii! =) The default mail app that comes with macs constantly crashed/didn't work for me, even after trying the fixes. So I downloaded the free one from the app store which seems to be functioning nicely. I was wondering why I was low on memory and found that 22+ gigs is in users/library/mail folder. Can I just delete the entire folder or would that... have any bad effects? I had no idea gmail saved things on my computer? I thought they were all saved in the internetz-world in gmail. thank you!
