deleting's a fantastic idea if you want to download the whole thing again if you upgrade. lite-C is turned into any version you buy depending on what key you stick in the folder. the key doesn't include WED.

as for making levels of your own WED style -- sorry i don't know anything about exporters or anything.

if you really want WED, i guess you know what you have to do. extra's cheaper, but i reckon commercial is more value for money.
