Is there any way to add all the guild members. to the members in dragonfly?

No not really to the actual members list as that does take registration and verification and such, but there was once an addon that I would like ported to 2.0 at sometime that would allow you to sync your roster members to dragonfly groups which was a big help. Not really sure what we will do this time around but I have been thinking about it by all means.
