pre-sales questions

I have a few questions I'm hoping you can help me answer. Let me explain first what I'm trying to do.

I have a number of menu items all pointing to the registration component. This gives certain users a special registration landing page. Based on this I parse the active menu id and fire a plugin (onUserAfterSave) to auto log them in or direct them to another payment form depending on the menu id.

1. Is this still standard Joomla registration? Meaning, the same entries in the com_users table gets updated (name, username, email, password)

2. Can I use multiple registration forms as described above?

3. Can my plugin described above still work?

4. Wondering if I can get rid of my plugin. Can I redirect and/or login user based on the registration form (assuming you support #2)? So I would need to be able to redirect/login per registration form.

1) Yes.

2) Yes, probably.

3) Yes, it will trigger the plugins.

4) Yes, you can, see www.sakic.net/news/selectable_user_group..._with_ajax_register/
