If no subject entered in post, default to "Re: Last subject entered"

[007]

That's sort of what I am trying to do.

Right now I have the newreply template with this in the title field:

<normalfont><input type="text" class="bginput" onFocus="this.value='';" 
onBlur="if (this.value=='') {this.value='Re: $thread[title]';}" type="text" 
name="title" value="Re: $thread[title]" size="40" maxlength="85" tabindex="1"></normalfont>

The way I really want this to work is probably more than you are willing to do, but just to give you an example, I want this to work is as follows:

Someone starts a thread called "test"

Someone posts a reply to it and titles it "yeah"

Somewhere in the postbit there would be a small link to "reply" to the individual thread.

when clicking this, it would automatically default the title of your thread to "Re: test" or "Re: yeah" depending on which one you clicked on.

Then if somebody just used the normal reply button at the botton of the page, it would simply be titled "Re: yeah" since that was the last title of the last post.

Then of course if someone typed in their own title in any of these occations, their own title would take priority over the default titles.

As you can see in the code I entered above, that automatically prepopulates the title with the main title of the thread. I would like for this to prepopulate based on the factors that I mentioned here.

If you, or anyone else wants to make this hack, I'd really appreciate it. If not then I'll understand. It does seem a little hard but you tell me. Thanks.
