I have been trying to search for an answer to a problem for the last few weeks. I found a question that was identical to the problem I was facing. However, there didn't seem to be a real solution posted to the question. I thought of contacting the original poster to see if he/she ever found a solution to the problem. However, the poster didn't have any contact information listed and I couldn't find a way to IM the poster. 

Since there was no way to IM the original poster, posting a question on the original thread itself seemed to be the best way to get more information short of creating duplicate questions. So I posted another question in the thread since the existing thread didn't provide sufficient information; perhaps the original poster just forgot to update it. However, my post was deleted by the moderator. 

So how do you try to find out more information about a problem that has already been posed before without creating duplicate questions and without having the moderator delete it?
