[HOT TOPIC] DW Q&A Integration in Buddypress Activity Stream

Hi Mostofa !
Of course, I can show you how we did it, please follow instruction below:
 
Step 1: Install BuddyPress plugin.
Step 2: Go to your theme folder (wp-content/themes/[theme-name]), and create a new folder, named it “buddypress”. Inside your new folder, create a new file: “bp-custom.php”. 
 
Now, open up the new file in notepad or any code editor, and copy/paste the code at this link : http://snippi.com/s/e4s59cg
 
Note: Please change ‘dw_simplex’ & ‘dw-simplex’ to your theme name
Step 3: Open the function file of your theme (wp-content/themes/[theme-name]/functions.php), and add this code in (somewhere at top of the file):

 include_once get_template_directory().'/buddypress/bp-custom.php';

Final step: Save the files and go to your profile page to see list of all questions on the new Questions tab.
 
Hope that helps!

I have this implemented and works well, thank you. However if I click on a users name, author page comes up. Like  mydomain.com/author/username. Is there a to change this as well ?

Finally i did it. now the Question list shows on the user profile. but while user click on answer button an error occurred.
Fatal error: Call to undefined function bp_blogs_record_activity() in /home/………/public_html/blog/wp-content/themes/dw-minion/buddypress/bp-custom.php on line 110
Please tell me how to fix it??

I would double check all your code and make sure that you have your active theme set right in the code that these guys gave us. All of mine works fine.

@ Dom ! Thanks for your help. I appreciate it !
@Debo !
I have checked your site, and look like it is working very well. If you want to display Question tab have style as our demo, You can open the bp-custom.php file, replace all the code in the bp-custom.php  file with new code:

 <?php
if ( function_exists('dwqa_plugin_init') && function_exists('bp_is_active')) {

Hi, i tried to use your solution, now its started showing in activity stream but there is one issue. in activity stream its says user  “wrote a new post” instead of saying user “asked a new question” same with answer, when someone post comment, again it says, commented on the post.
