Now that I have looked at every stsadm command, I have noticed a few inconsistencies.

---
This one seems to be a bug

Stsadm –help forcedeletelist

Results in

stsadm.exe -o forcedeleteweb
-url <url>

But stsadm –help forcedeleteweb indicated no such command exists

---
In all but one of the following, zone comes before url

addzoneurl
deletezoneurl
enumzoneurls
geturlzone

---
blockedfilelist had an add and remove parameter, unlike all other operations that would have suggested that, this should have been 2 seperate operations, addblockedfilelist and deleteblockedfilelist.

---
Where is the enumblockedfilelist?

---
I have most of the commands documented now.

Some refinement of the categories still to come though.
