When a post creator hits "Send Post" and if there is a unexpectedly slow response because of a temporary stall, slow pipe or outage and they click on "Send Post" a second time......viola.....double post.
Is there an easy fix to prevent the double post from occurring?
You know, there was a post here a year or more ago about using javascript to prevent duplicate form submissions, but I can't find it right now. I did find some results with google though, just not at this site.

The solution posted here at bbpress.org was similar to this one (at the end):

Hi,
I'm using 1.0 alpha 2 and had the same issue and used this to disable the the button and change it's label/value after submission.
On the edit form, replace:
<input type="submit" id="postformsub" name="Submit" value="<?php echo attribute_escape( __('Post Message') ); ?>" tabindex="4" />
with
<input type=hidden id=hidden1><input type="submit" id="postformsub" onclick="this.disabled=true;hidden1.name=this.name;hidden1.value=this.value;this.value='Please Wait...';this.form.submit();" name="Submit" value="<?php echo attribute_escape( __('Post Message') ); ?>" tabindex="4">
This creates a hidden form field which the submit buttonvalues are passed to before it's disabled, as when it's disbaled it won;t work as a submit button.
I hope that helps.
I similar thing can created on on the edit form.

the WITH replace code does not seem to appear corectly - I think because it had not spaces. here it is again:
<input type=hidden id=hidden1><input type="submit" id="postformsub" onclick="this.disabled=true; hidden1.name=this.name; hidden1.value=this.value; this.value='Please Wait...'; this.form.submit();" name="Submit" value="<?php echo attribute_escape( __('Post Message') ); ?>" tabindex="4">
