Managing users with no account on website

We have a community sports website that I manage. We allow uses to sign-up for our club and participate in events.

Currently each user can setup a profile on our web. They can then log-in and sign-up for tournaments and any events we have using the profile.
We also allow people to send in a manual registration form.
Users who send in manual registration form, how should I manager them?

Any suggestions?

Thanks in advance.

You can already manually approve your new member signups.

If potential new members are sending you something first, like their profile details, then you can manually send them the link to your signup section.

However, you can’t manage all your visitors on your site, only those users who wish to sign up and login as members or those who contact you for some reason.

You can of course always approve new members by email or token etc.

Is there a way for me to register an user manually since I have his/her info and sent the user a web link to activate the account and then change the password?
This will ensure I have data for all users (who registered and users who sent a printed from) in my database and user can decide if they want to using the website or not.

Right now I have Site_Members database which recognizes a user based on “_id”, if I manually type in the info of the user the IF wont match if the user wants to signup. If I can register them in my database and allow them to change password so that the “_id” is the same it would work perfect.

Anyone have any suggestions?
