I'm not trying to prevent it.Pleae stop trying to prevent DIY work or, if you must continue on that project please explain what happened to make you so adverse to DIY work.
Have you never seen the number of times I tell people that they should be competent, or the number of times I am criticised for wanting competence?
For you to say that I am trying to prevent DIY work means that either you are stupid or you have decided to join the cabal of petty and juvenile morons here who like have a go at me for their own pathetic amusement.
