Foren / Cotonti / Development / Using Ajax and Jquery (Question)

I am making an plugin were Ajax and Jquery are needed...
BUT Cotonti has settings like :

• Activate Jquery
• Turn Ajax off..

I think any website needs nice JS tricks (JQuery magic)
Ajax is also a thing off web20,RIA.


But if this is set off in the config, will my plugin still work ??
(If not, what should I do.. go back to old school programming ??)
Another thing... Are there still sites out there that doesn't use these techniques ??
