this plugin is really great in my opinion, but is has one des-avangage..
the poor sharing by email handling...
the most of users using gmail, yahoo, windowslive etc web mails and the they dont use -the most of them- any pc or mac based email client.
so, they have all the contact in there. the goal of asharing, is to sharing the most, right? if the user has ALL the contact in a readable place, it is more possible to share in more people, and give us the more traffic.
one good solution is the solution of the sharethis plugin.
it is NOT attractive like flare, but is has a great email handling!
i want to use flare, but i think you must re-write the email part.
is this possible? are you planning to do this?
