this is all about theme template files… so you will need to open up the appropriate template file and move the template tags (ie function calls) around where you want them… or delete them if you dont want them…
most of the template tags are pretty obvious, but holler if you dont understand… these template files function just like a wp theme template file…
the thing you called the function bar will be in the spHead.php template file… thats where the profile, subscribe, etc button are…
the add topic and add reply button are specific to views (while spHead.php is all views)… spForumView.php will have add topic button template tag in it… spTopicView.php will have the add topic and add reply buttons…
so you just need to familiarize yourself with the template files and do what you want with any template tags or simple php or html code…
again, holler if you have any questions…
