Indeed... threads are a lasting resource and should be treated that way by OP’s and by subsequent contributors.   You might not have been the first person who had the misfortune of having encountered this problem, but, thanks to your informative posting, you might well be the last.   This is one of the reasons why it is a very good practice to, say, edit your original post to clearly say Solved (see my comment #x on xx/xx/xx), but otherwise to leave the content exactly as you originally wrote it.   Then, add a separate follow-up reply to the thread, which details the solution in sufficient detail that a knowledgeable stranger can follow in your steps.

In this way, when I or anyone (perhaps many years later...) search for the post, I can find both an original panicked description of the problem (yeah! that’s me!!   this post is going to help me!), then I can find the solution.   If there was debate or discussion or clarification that lead up to that solution, I have access to that information, as well.

Aside from its value as a brief interlude between the morning coffee-pot and the start of the work day, this is where PerlMonks really shines:   as an informational resource of many years’ running.
