re: Mike's comment query on plagiarism:
I assume by plagiarism, you mean people copy other peoples comments, rather than linking to them, but the points awarded are no different from linking or copying, so what is the point - is this just for the prestige of passing this off as your own knowledge, or do you mean something else by plagiarism?
I am assuming "plagiarism" here refers to passing off someone else's comment/work as your own.
Referencing/linking/quoting the manual, or even someone else's comment is not plagiarism, as it still helps the original poster eg: as in many cases, where the OP appears to be too lazy *cough* or possibly otherwise unable to find the original references/document(s) on their own, so although it's the same information, it's still valid to say this was the solution (the "solution" being to search/read existing documentation)
example: OP1 posts a problem, TA1 replies with solution to look at pNN in manual, do steps X, Y, Z
OP2 then posts similar problem
Scenario 1: For OP2, TA1 can either copy the text from OP1's post; or link back to their soln on OP1's post
This is valid, as if OP2 had searched/read OP1's issue, they may not have had to create their post in the first place. TA1 still gets extra point/soln for helping.
Scenario 2: TA2 posts link back to OP1's post saying "solution here as provided by TA1" (or can copy text giving credit to TA1)
Again valid, TA2 gets point as this still also solves OP2's issue while giving TA1 credit. Ideally OP2 could vote up TA1's solution post too, but hey, baby steps ....
Scenario 3: TA2 cuts & pastes TA1's text from OP1, and gives that as solution to OP2 with no link back to original issue
I would regard this as plagiarism, as this would be TA2 passing off TA1's solution as their own.
(obviously TA2 could be any user, not necessarily a TA ... but you get the idea)
For some problems the solutions may always be similar (ie: always run same commands x, y, z), so there may be many solutions that may effectively be the same thing but may not necessarily be copied, it's literally just the same solution, so it's a bit hard to get around that - from Craig and Brian's responses it sounds like there have been cases where something has been deliberately/obviously copied though (eg: Brian mentioned screenshots - that sounds fairly deliberate unless the other person has configured their system the exact same way...!)
