Subscription and registration form

[Mini_me]

Hello!

I have a web site (www.winner.gr) and I'd like to add a login system where the customer will be able to enter their username. and password. after they have subscribed for free. also in the login part I'd like to place a link that will send to the user his/her password in case they have lost or forgot it,like it is in yahoo for example.
What do I need for this, do I need a database or something and how can I connect all this functions together?
How much time will it take?

Thank you so much!

Mini me, you didn't state what platform you're using, but here are some PHP examples from the Hotscripts site of member login scripts

PS. Next time you post, try not to use all capitals, it's considered as shouting in internet circles. I have edited your post to "normal" capitalised text.
