Spitoon & Gonzo make some very good points: I would add one more, FWIW.
Whilst the internet is a very useful tool, & forums have their place, there is always a risk that the information quoted as fact, may well be just opinion. It may also be irrelevant, if based on incorrect information, or information pertaining to a different rule set, say in a different country. If in doubt, there should always be someone in your training department, or back at your original initial training centre, who can help you sort it out - don't be afraid to ask in case "you should already know that": if someone says that, move on to someone else, since no-one knows everything & they've just demonstrated that themselves...
