Just to elaborate a bit on this functionality: We added in 15.7 on the pre-responsive skin the admin option to show who accepted a solution (Here's the associated release notes: https://community.lithium.com/t5/Release-Notes/15-7-Release-Notes/ba-p/202212#float ). This feature didn't make it across to the responsive skin though. You can create a custom component using the API call VikasB outline to obtain the data on who accepted a message as a solution. Technically you would check if the current message is marked as a solution and then obtain the author information via passing the message ID to the API v2 call
SELECT solution_data FROM messages WHERE id = '120288'
which would return you something like the following that you can format accordingly then:
{
"status" : "success",
"message" : "",
"http_code" : 200,
"data" : {
"type" : "messages",
"list_item_type" : "message",
"size" : 2,
"items" : [ {
"type" : "message",
"solution_data" : {
"type" : "solution_data",
"message_id" : "439",
"accepter" : {
"type" : "user",
"id" : "31",
"href" : "/users/31",
"view_href" : "/t5/user/viewprofilepage/user-id/31",
"login" : "admin"
},
"time" : "2016-06-23T14:32:26.000-07:00"
}
} ]
},
"metadata" : { }
}
