Parameterize Activation link?

Hi,

I want make load test on the registration page in my tested web application.



Scenario is



1-write url then go to loginPage

2-click to I want registration

3-These are the textboxes I need to fill an Post via "Complete subscribe" button:Name,surname and mail adress

After registration complete the activation link goes to e-mail.



I can give parameter to registerationPage but how can I complete activation for each Vuser.The activation link is uniqe I can get activation link from database.



But I don't know how I can goes to this link for each Vuser than input data to textbox(password,gender,birthdate etc.) for load testing.



I wonder can be done with scripting ? Eventually I have activation link for registeration!



If you have a visual or a simple solution about that please let me know.



Thanks.
