Ive noticed that sometimes a thread is just locked without any explanation.
Wouldnt it be better if the mod/admin who locks the thread gives a reply (even one line would do) as to why the thread is being locked. It would tell us who locked the thread and the reasons for it. Sometimes it seems a thread is just locked for no real reason. It shouldnt be too much to ask.
Most times when a thread is locked, the reason is quiet obvious. Either the conversation has been derailed or the calibre of discussion has been reduced to name-calling, mudslinging etc.
If you really need to know, you can always PM the moderator of the section with a reference link and ask for an explanation.
