Could you please specify what do you mean by 'random users'? What algorithm of users randomization should be used?

umm...  just display a random selection of users from your site... not sure how else to explain that. not sure what algorithm... probably just use MySQL's  RAND function???

SELECT * FROM ow_base_users ORDER BY RAND() LIMIT 12; etc... 

We do not recommend to use the RAND function because if you have a lot of users, this function will extremely slow down your site performance. The best way to achieve this is creating the script with the definite algorithm by which the system will select the users and show them in the random list.

Anyway, you can easily create a new users list using the existing lists. You can see how it works in /ow_system_plugins/base/controllers/user_list.php file.

Thanks I'll look into that. I didn't seem to have a problem with in using this method in my previous system and 45k users...

What's a lot of user's in your mind?

Hmm, 45k it's quite huge community. We do not insist that you shouldn't use the RAND(), but we must advise about the negative consequences.  As I said, you can check the existing profiles lists to see how it works and how to add an additional list, but it's up to you to choose what functions and scripts use.
