Hello and welcome. Here are some basic guidelines for conduct in the forum.
Don't be a dick.
Serious responses only, no trolling etc.
If you don't like something feel free to say so, but try and keep it positive. For example discuss why you don't like it or why it doesn't work for you, what could be improved upon etc. Everyone is entitled to their opinions, and it is these opinions that we seek to help us progress with our work but simply saying something is not good or you don't like it isn't helpful!
that is all.
