== Discussion format == 

 Hi, Doc.  Just in observing your comments on discussion pages, I thought I'd point out something you may not have known.  To prevent text from getting all strung together, it's usually best to left-indent your post one more tab stop than the post above it.  It's not a policy or anything, but most people do it - it's just easier to follow a conversation that way.  All you have to do is put a colon (or two or three or more, depending on how many tab stops you need) before your post. 

 :Like this. 

 ::When you do this, it makes conversations easier to read.  I figured you just didn't know, so I thought I'd point it out.  Cheers.
