Before </head> tag:

Inside <form > tag (as an attribute, not a sub-element):

onsubmit="MM_changeProp('UniqueButtonName','','disabled','disabled','INPUT/SUBMIT')"

 

 

(...deleting "oh I accidentally pressed the submit button 9 times while I was waiting" posts hurts my brain.)

So you made it so you can't submit it more than once? Brilliant... except that once the forum crashed, and I had to keep checking. That would ruin it, I'd have to copy/paste it.

Edit:

I just tested it here. It doesn't work.

Thanks sayo! I'll impliment that later this evening.

If I'm making a large post, I always copy+paste to notepad just in case.

Tested what?
