For this page to make any sense, you need the userscript to actually do the randomization, which is at: User:Leijurv/randomizeList.js. You can get it like this (by adding importScript('User:Leijurv/randomizeList.js'); to your common.js).
This is a normal list:
- A
- B
- C
- D
- E
- F
This list, on the other hand, is marked to be randomized per-viewer by a specially classed P tag immediately beforehand
- Some user 1
- Some user 2
- Some user 3
- Some user 4
- Some user 5
- Some user 6
- Some user 7
- Some user 8
This one is too
- A
- B
- C
- D
- E
- F
- G
- H
- I
- J
- K
Logged out users will see the list in its original order. Logged in users will see the original order for a tiny amount of time, since userscripts do not load instantly.
Here's an example of a list that might have more items added to it over time:
Start with just A
- A
Then add B
- A
- B
Then add C
- A
- B
- C
Then add D
- A
- B
- C
- D
Then add E
- A
- B
- C
- D
- E
Then add F
- A
- B
- C
- D
- E
- F
Then add G
- A
- B
- C
- D
- E
- F
- G
Then add H
- A
- B

Then add I
- A

Then add J
