E-mail on replies
 

How can i set it so members get an e-mail wen sum1 replies to their thread as standard, cant find it in the options...

It's there. Under user cp > options, you should see this.

Use 'Email Notification' by default?
Using this option emails you whenever someone replies to a thread that you have participated in.

Thanks...

No problem. :)

cant find it in my options though....

which one is it....

In the admin options (what you listed) set the following to yes.

Then each user can turn it on or off in their user cp on the board. Hope this helps. :)
