Allow members to choose font size?

[Erwin]

I see what you are asking for.

Instead of the font code above, use this one:

<font face=Verdana size=$bbuserinfo[fieldx]> and </font> with your $post[message] in between (x being the custom profile field id).

All post will be set to each member's font size.

As for quote tags - you can do the same in your custom vBCode section by modifying it there.
