We, on the TFL Staff, have always maintained that making a thread into a "sticky" thread is the best way known to man to hide it!
Look up a few threads in this very forum and you should find one titled, "How do I quote from a post". Post #4 in that is very informative and includes some additional tips on making quotes even more useful.
I realize this was moved from a different forum, but for future reference, the Tech Support forum is always the first place to start when asking questions about posting, etc.
