Random Number

[RateU]

Depends whether you want the random number is "static" or not.
What I meant by "static" is, it won't generate other random number after the thread is submitted (the random number created once while the user submitting the thread, so every users will see the same random number when viewing the same thread). The random number will be stored in db. For this type random number, you can use XThreads.

If you want it to be dynamic (each user will see different number, even when viewing the same thread), you can use Template Conditional.
