As we reply to some threads by default we get subscribed to those threads... but sometimes we dont want to return to those threads.. but unless they are subscribed so when they are updated in they automatically shows up in usercp creating a crowd of threads... so i personally think that there should be an option of check or uncheck the subscribed option... by default the option should be subscribed but atleast the user should have option to unsubscribed while posting.... hope this suggestion is of help....
It is an option. Instead of using the Quick Reply, click Go Advanced. You'll see the option to not subscribe under the reply box.

Jerlene.net is correct... Though, if you don't want to subscribe to most of the threads ya post in then: userCP > Edit Options > Default Thread Subscription Mode (it's the second block down) and pick your subscription level. You can pick DO NOT SUBSCRIBE then take the advice from Jerlene.net and subscribe on a post by post basis.
