Advantage is obvious!
If there is a field user didn't fill up, you can notify user about it and
ask him/her to fill the field up.
Do the math:
Validating after send:
1. Fill in the form
2. Send
3. (Load)
4. Validate
- It failed = back to form
5. (Load)
6. Pre-fill the fields up with previous values
Repeat 1 to 6 untill user gets everything right
7. Do what you want with form data
Validating before send:
1. Fill in the form
2. Validate
- It failed = info to user if something failed
Repeat 1 and 2 untill user gets everything right
3. Send
4. (Load)
5. Do what you want with form data
Ofcourse this does not apply to every form, but basicly this is how it goes.

Yeah, before sending it. Just wondering what the advantage is in validating
before sending.
