topic_index.html has the text I want to edit
{capture name='info_string'}<a href="{$avatars[$post.userId].url}">{$avatars[$post.userId].title}</a> <span class="ow_tiny ow_ipc_date ow_remark">{$post.createStamp}</span>{/capture}
And I'd like that to be {$avatars[$post.userId].title} - ({$usernames[$post.userId]})
Is there a globally accessible variable or function I can call from smarty to access this?
