select import

This should be done from the invite module not from dcl_importer.
the module is basically grabs the contact list from the target service provider and after that it handles them to invite which in it turn will take everything after this step.

anyway, i will see what i can do regarding displaying the checkboxes and the check of the registered emails.

Ma'moon

there should be a way to select checkboxes for emails to invite
Agreed. I think it would be great if dcl could implement this. Other modules despite invite could really benefit from this feature. Solving this within invite wont.

also a check should be done to exclude emails already registered

also there should be a way to tell users which emails are already registered

The last two should be checked within invite and i think this already is the case. Not that they are not imported but as far as i know invite checks on already registered users during the invitation process. Furthermore i have no idea on how other modules might implement dcl_importer functionality. Blocking already registered users by default might not wanted/needed.

I believe that it would be nice to provide the admins the options to select between the current way of handling the imported emails by invite directly or displaying check boxes, i will give it a shot and see what can be done regarding this matter.

it seem that, we have a hot feature request. we have 3 duplicate feature request. should we just focus on one thread ? say the latest one -> http://drupal.org/node/184538

i am marking this as duplicate, please refer to the above link.
