No problem, Chelle! Yes, NARGS is an excellent organization for anyone interested in alpine and rock gardening.
Here's the general forum - lots of good info there on rock gardening and on gardening in general, plus various other interesting topics (photo essays on specific species of rock garden plants, photos essays of alpine trips, etc.):

Here's the main website. There is also a very good index here of alpine plant photos (see NARGS Photo Galleries) - very useful for anyone trying to ID plants... or just to incite plant lust!
