Hi Mac. I'm told that a "permanent thread" is one that will stay on the current forum, to let newbies know how info like this is discussed on Mudcat. I've spoken to Leej and Joe about doing a bit of editing on this one so that only the tips are there. I mentioned this at the beginning. Max is putting together a number of "permanent threads" on different topics.
No reason someone else can't start another dozen "instrument tips" threads. I'm glad folks are finding it useful.
