The list of approved tags is not complete. I
imagine PRE was left out on purpose, but why list the
tags if it isn't a complete list and there's a link where
a complete list is available? I'd rather see that space
used for something else--in my experience trying to use
unallowed tags is something editors rarely have to fix,
the misuse of PRE tags (which is why I think that
the line about CODE tags should be listed before
posting in the wrong place (maybe SOPW should
be listed first, as it is where most people should post),
people who aren't logged on (when they want to be),
and poor titles. I'd rather see the things that
cause the most work addressed in the limited space
than the things which
are automatically taken care of.
I agree with the person who suggested the mention
of search and super search.
I left out PRE tags because they were listed twice in the line about CODE tags and I wanted to emphasize the use of CODE tags so having PRE tag listed 3 times versus code tags only twice seemed wrong, (I admit I was tempted to leave PRE tags out entirely but decided not to for the very reason you pointed out). As for why did I list them in the order I did? No better reason than I was trying to mimic Vrooms original showhints() order.
Once again though for many of your points and the others listed (well, the supersearch one is an entirely different question as it requires changing a different piece of code) while excellent they just dont work out for space reasons. At some point theres a tradeoff between pointing something out in the space that will be seen and putting in so much that half of it is overlooked.
Still your point about the code tags susggestion going first (my origianl plan intil I noticed it changed the current order) is a good one and if I find a minute perhaps Ill give it a whirl to implement some or all of the suggestion you and everyone else gave.
