Info I found out on completing the:
'Post a comment and obtain more than 2 Likes' Daily Goal for +15 Exp
==========
The likes must be MOBILE ONLY
desktop users likes doesn't count
.
Your OWN LIKE counts towards that number
.
It is +15 Exp
.
It auto completes the 'Add a chapter comment' (basically post a comment) Daily Goal on the DESKTOP list without giving you an extra +5 Exp
(Will test doing Desktop before Mobile Dailies another day)
