how to display more than one group icon in posts

[perplexed]

I realise this will not be popular with a lot of people who want to keep the space clean and uncluttered, but can someone tell me how to display more than one group member icon under a poster's name on posts?

I have a number of groups but specifically I would like to display the additional groups because of the Mod groups.  I would like the new mod group icon to be displayed but also to have their other group icons displayed too as they have significance on the board and it will help the other members.

At the moment only the primary membership group icon gets displayed.

Can someone tell me what to do to change this?

I am using the new beta version of smf

thanks
