This is perhaps an idea that can be developed in a new version of Dolphin.
One of the reasons I chose for Dolphin is the usability to manage the users. However, and I'm really missing this one:
A function to create new users.
I'm moving the whole old site from ELGG to Boonex now and I'm troubled to get all the current users to the new site. If I just ask them to create a new account, half of them would 'forget'. And creating 6000 accounts myself is a big job.
Just my opinion, my 2 cents if you may, on how Dolphin would be even better :)
