In qa-app-options there is the following function:
Returns true if the home page has been customized, either due to admin setting, or $QA_CONST_PATH_MAP
return qa_opt('show_custom_home') || (array_search('', qa_get_request_map())!==false);
Based on the comment, and the function it indicates that it's possible to set a custom home-page in question2answer. I can't find any documentation on how to do this programatically, or in the admin-settings. Could someone please point me in the right direction?
