all the information is output via template tags… so you can remove, add or change the information…
in this case, it looks like you are displaying forum ranks (new member, moderator, etc) and usergroup memberships (member, moderators, etc)… if you have defined badges for the ranks and usergroups they will already display (by default in our themes)…
any changes to display information is done in your sp theme in use… in this case, since the this is in topic view, you would edit the spTopicView.php (for default, might be similar but different in other themes) template file and make your changes… in particular, these two calls:
sp_PostIndexUserRank('tagClass=spPostUserRank spCenter');
sp_PostIndexUserMemberships('tagClass=spPostUserMemberships spCenter');
as I said, by default, badges are already displayed if you have them defined on forum – components – forum ranks and forum – usergroups – manage usergroups… if you just want to remove ranks and memberships, just remove the template tag calls… you can just display titles or badges or both…
for what else you want to do, you will have to be more specific…
and dont forget, as always, before editing an sp theme we provide, we strongly recommend you make a child theme or a custom theme…
