Sweet. How about:

<CommerceChangeDoubleTimes/>
and
<ObsoleteSafeCommerceChanges>

Here try this link (http://www.civ4wiki.com/wiki/index.php/CIV4TechInfos).

Ummm. Yeah. Not there. They're from the buildinginfos, and I'd already looked at the Wiki page on that.

From the Wiki, about CommerceChangeDoubleTimes' effect:

Unsure? (Many Buildings) -

DoubleTime affects how long (if ever) you have to wait for the commerce bonus from a buinding to double (libraries will eventualy double to produce 4 culture instead of 2). Obsolete safe affects primarily wonders and I belive it prevents the cuture bonus of the wonder from being lost when the wonder goes obsolete. Both tags only affect linear commerce bonuses not % based modifiers.

Thanks, Impaler. I'll add that to the Wiki sometime if I remember. :)

Interesting about the doubling - I suppose it was added as a way to counteract inflation, huh? Odd it never got any use...
