Hi All… have made the following adjustments in themefolder/buddypress/activity/post-form,php from line 20. Basically what this does is change the greeting in the activity whats new content post area for either the wall, a group or posting on another users wall. Use this with the free BP Activity as Wire plugin, which allows you to post on a friends activity wall as you can do in facebook.
<p class="activity-greeting"><?php
if ( bp_is_group() )
printf( __( "What's new in %s, %s?", 'InspireBook' ), bp_get_group_name(), bp_get_user_firstname() );
else
printf( __( "What's new, %s?", 'InspireBook' ), bp_get_user_firstname() );
?></p>-->
<div id="whats-new-content">
<div id="whats-new-textarea">
<textarea class="bp-suggestions" placeholder="<?php if ( bp_is_group() )
