Thanks for that, Adi. I posted some extra stuff on the chatbox, but best just forget about that, because I'll post it here.
1. It would also be very cool if you could correct the replacement of every quote mark from the old system with "
It looks like the forum software actually parsed what I wrote. Where the " appears, I actually wrote (without spaces) & q u o t ;
In both the chatbox and the forum, this appears to parse and print the appropriate symbol, when you post, so it appears that the forum recognizes the correct symbol, but hasn't processed the stuff from the database yet.
On the other hand, it seems TO have processed the (without spaces) B ) string, which appears as a smiley with glasses, or a

. Because the forum has replaced many instances of lettered lists of propositions with smiley prefaces. Which is annoying for philosophers like us!
There's also the & symbol, which appears in the old forums as & a m p ; (without spaces. There may be more. I'll keep reading the old forums.
There's also the matter of the new forum formatting code. It seems to accept square bracketed formatting code tags, but not angle bracketed ones. That's fine. Except some of the formatting buttons furnish angle bracket tags. Even the quotereply button gives you this (without spaces):
<strong>zero wrote:</strong>
[ q u o t e ]Whine, moan, gripe, I'm a bloody ingrate.[ / q u o t e ]
As you can see, I didn't have to space the angle tags, because they didn't parse.
The buttons on the boardcode bar for the post page give the following tags:
bold.................. <s t r o n g>< / s t r o n g>
italics................< e m >< / e m >
underline..............[ u ][ / u ]
strikethrough...........[ s t r i k e ][ / s t r i k e ]
subscript...............[ s u b ][ / s u b ]
superscript.............[ s u p ][ / s u p ]
fontsize.................[ s i z e = 1 ]text size[ / s i z e ]
color....................[ c o l o r = # F F 6 6 0 0 ]text[ / c o l o r ]
etc with square brackets until...
unordered list............[ u l ] < l i > text < / l i > [ / u l ]
ordered list..............[ o l ] < l i > text < / l i > [ / o l ]
list item.................< l i > list item < / l i >
etc with squares, until...
code display.............< c o d e > code < / c o d e >
