Bro,
The whole idea of the forum is to help others, so that reefers become more conscientious.
Some may "sound' cocky (not refering to you). It was because of the efforts and results they went thru and the trials & tribulations that they had under-gone. If you take it negatively, it's arrogance. On the positive note, it is pride. Any which way there are always something to learn from them, if one chooses to.
