2. Unable to set Group Admins

Fix:
controller/groups.php

Find the line:
if( $group->ownerid != $my->id II !isCommunityAdmin() )
change to:
if( $group->ownerid != $my->id && !isCommunityAdmin() )

3. Groups: Only 20 members receive notification emails
Look for few instances of (roughly line 1901 & 2140 )
$model =& $this->getModel( 'groups' );
$members = $model->getMembers($groupId);

replace with
$model =& $this->getModel( 'groups' );
$memberCount = $model->getMembersCount($groupId);
$members = $model->getMembers($groupId,$memberCount);

4. Video not Playing:
Video not playing if single quotation mark exists.

Fix: http://www.jomsocial.com/webforum/viewtopic.php?f=43&t=12064#p66987

Kindly open and edit this file:
JOOMLA\components\com_community\templates\default\videos.flowplayer.php
Find this line:
title: '<?php echo addslashes("'", "", $video->title); ?>',

And replace to this line:
title: '<?php echo JString::str_ireplace("'", "", $video->title); ?>',

5. Creating Groups:
Creating Group gives DB Error 500

Fix:
Problem is actually because the file /com_community/libraries/featured.php did not include the core file. If you are having similar problems, edit that file and place the following codes at around line 2,
require_once( JPATH_ROOT . DS . 'components' . DS . 'com_community' . DS . 'libraries' . DS . 'core.php' );
