Well I think I finally got it somewhat.
Here's what I finished with.
I also have "quickedit, mutiquote, and quickquote" so it is different from
the standard template even before the change.
I'll do a file comparison and try to get back and post directions.

OK I think the main thing is placing the "rowspan" in the right place.

I must have misread something somewhere, because after reviewing,
it's almost identical to what Sledgstone posted. ??

I made my own version of this one, and was going to post it as a mod when I discovered this thread.

You can try my version and see if it is better for you.

It is made on an unmodified postbit_legacy template

Can I offer praise and worship for this modification? That sig thing was driving me crazy. Thank you very much.

This is great, accept for it seems to create a line that goes right across the postbit_legacy underneath the message, is there a way I can get rid of this?

If you take off the cellspacing="1" for that table, it'll remove the line, but it will also take out the border for the entire postbit_legacy. I didn't care for it at first, but my members like it. O_o They say it helps distinguish whats the post and whats the signature.

Thank you! But I would like to keep the border in :o but not have the line below the message and above the sig, is there anyway to get round this?

does anyone know if this would work in 3.6.x?

I was looking at a few threads/posts about this yesterday but none of the mods succeed properly.

I'd appreciate is someone could release this mod for 3.6.x

I released this for 3.6.x in the following topic:
