In this step do you only replace

on any other line except this one: (

PHP Code:

dont edit this username if it look likes this) <img src="{vb:raw userinfo.avatarurl}" alt="{vb:rawphrase xs_avatar, {vb:raw userinfo.username}}"

  step 39 go to AdminCP > Style Manager > Your Style > Activity Stream Templates > (Edit all files listed below)
   
   activitystream_album_album
   activitystream_album_comment

   step 40 find >  username   and replace with this for all templates   musername 


All the templates I've looked at have the line you say not to touch, I take it you just look for any others except the line you mentioned?
