Remy,
YES, preview on this site is critical ! I frequently add Links or Picks, and
not knowing any more about computers than I do, I always preview to
check if the Links actually take one somewhere useful.
With the 5 minute rule, it just (IMHO) puts one under a lot of pressure to
get it absolutely right the first time. I admit I've not posted on some
Threads, given how complex that Post would have been.
