Make your points on people's posts constructively and with respect.
this is very necessary and I don't see any reason why an old member can't advice a supposed newbie in a matured and responsible manner.
One of the major concern I also have as it relates to matters as this is that their are people that have prior experience as it regard bitcoin and cryptocurrency but might not have been an active member of the forum, and then they now join the forum and make a post that is matured and shows how experience the person is, you will see numerous attack on the individual as though one cannot do his research and get lots of information that although his account might be showing newbie or jnr member, he could be more experience than some legendary.
The journey in the forum is one that takes time and no one should be discouraged just because he is joining the forum as a new person. If they spam or make a faulty appearance in the forum, let's first direct and guide them responsibly and when they seem not to be taking the advice seriously, they could then be shunned it reported in reputation board.
let love lead
