Q&A – WordPress Questions and Answers Plugin– where is the ask a question button

Hi

I am using Buddypress social theme on site weldbook.com and i have activated Q&A plugin. Now i do not see on the member page or anywhere on front end of my site where a user can click and ask a question

how will an average user (subscriber ) or even admin or authors ask questions from main website

it their a button or switch ( As a question ) by which user can ask a question

best regards
