I understand that it is very [i]verboten[/i] here to create new topics on subjects that have already been discussed, but I would like to submit the following as an example and ask if I have acted properly in this scenario.
For the last day or so Search [u]has[/u] been working for me (though that was rarely the case in the past). I did manage to find [url=http://www.prometheus-movie.com/community/forums/topic/2616]THIS TOPIC[/url] from over a month ago that is relevant to footage analysis that I've done much more recently than that. So, trying to follow the rules as I understand them, I posted there. My post of May-06-2012 12:54 PM is the one I'm referring to.
I find it very unlikely that anyone will ever see this information that I posted because it is buried so far back. Is there any way for me to know (to proactively check) that people have read it and not found it worthy of any commentary (because my posting it has produced no new activity in that topic)?
If I had posted this information as a NEW topic, would it immediately have been locked and dismissed because others (before I ever joined this site) had already discussed it?
I honestly do not understand HOW this is supposed to work.
I'm trying to be a good citizen of this community, but I don't know how in this case.
