"What's new" string in activity post form shows only first word of name

How to replicate:
WP 3.5
BP 1.6.2

1. Go to profile, and change the name so that you have two words or more in your display name.
2. Go to activity page. The activity comment will show, "What's new, ABC?", where it only shows the first word of the display name.

This has always been like that.

The rationale behind this is so it would emulate a first name. If you don't like this, you can either:

1. Filter 'bp_get_user_firstname' so that it returns the full display name instead of only the first word of the name; or:
2. Change the function call (from bp_get_user_firstname() to bp_get_loggedin_user_fullname()) within the template (activity/post-form.php) to use the full display name.

I would like to try your workaround.
Where is activity/post-form.php located?
I cannot find a folder called activity nor the post-form.php template.

If you are using ​a child theme of bp-default, copy /wp-content/plugins/buddypress/bp-themes/bp-default/activity/post-form.php to your theme. (Make sure you keep the subdirectory structure intact.)

Then, make your changes in your theme's post-form.php.

Thank you very much. The workaround (renaming tobp_get_loggedin_user_fullname) worked!
