It may be that neither Lee nor any Mod locked the discussion. In fact I have just looked at it and it isn't locked.
What you may not know, is that when a thread reaches 13 posts, (I just counted them, ), that thread will reach a limit and will cease to accept more posts. You get the;
''Note: Due to the depth of this discussion thread, no additional replies can be accepted. If you have comments to make, please reply to the original post at the beginning of this thread.
This is a nuisance I know, especially when you're in the middle of a discussion, but there has to be a limit otherwise the thread becomes too long to display and starts disappeaing off the edge of the screen, and re-appearing on the left.
The way to get around it is to start a new thread, (note I don't mean create a new forum discussion), within the same discussion and head it something like, ''Continuing long thread'', etc.
That way Amos you could still have replied to Jonah within the same discussion.
Of course, you may already know this, hence I'll shut up! <grin>.
