If someone posts something asking for advice or help please don't try and bring the person down by commenting how there Grammer is wrong. If you don't understand the grammer or even if you don't like the topic, then just move on without saying anything. People post on these forms looking for help and advise. Treat everyone as you would want to be treated! And if you don't have something nice to say, then don't say anything at all.
Thanks Have a Great Day! :)
