1. Issue with Like's displaying the wrong username in Easysocial notifications mentioned here already:

2. BBCodes are not being stripped from the text when the search summary text is created resulting in ugly summaries.
3. Discussions are not getting removed from the search index when they are deleted from within Easydiscuss front or backend.
