The sign-up procedure we have on http://gtalk2voip.com http://gtalk2voip.com is very simple and quite unique: no new login names, no passwords, not even an email address, but a working IM account. All user has to type in is his/her GTalk/MSN/Yahoo/AIM or ICQ id. Upon submission our system instantly sends back an IM message right to user's messenger with a unique link to his newly created personal account page. Since we don't have authorization per se (it's done on the messenger side when user signs-in into IM account), the percentage is very high, I believe 50% or even higher. One of the advantages is there's no need to remember another, most likely useless, login name and password. ;-) The other question I would arise is what is the percentage of active users you have. I have a feeling that most sites and services keep on in their DBs up to 95% of dead souls -- those who once tried and never returned.
