There are some really helpful people in this forum, but the majority are obnoxious self-serving w*nkers. They are more interested in just showing how smart they are, more so than helping novices like myself. @jmcilhinney in one or the worst I have ever come across, he needs to have a reality check on what decent people are like, instead of trying to show his supposed intellect, avoid like the plague.I have trained dozens of apprentices over my 44 years as a tradesmen, and do don't ridicule them, treat them as fools etc a valuable lesson can be learnt. These people nerd to realise that people like me, fix the things that these "Experts", (and I use that term very loosely) use daily that THEY are incapable of fixing
