Saying thank or not doesn't make any difference. I know you are a newbie and may not really get it. One of the best ways to say thank you is to in my opinion help other newbies answer their questions and give them proper directions wherever you can. It would make the forum a better place.
Do not let anyone mount pressure on you to tell you that you need to send merits to a user as a way of saying thanks. We don't really care for all these things because either way merits will come when someone finds value in what you write.
Please stop replying each post individually
Thanking someone personally is what almost all users do. I did it alot in my newbie days. Even till now I do it. If I don't have merit to reward a post that help me, I will say thanks. Some times, it could be a 1 line thanks or below a post by quoting it.
Newbies coming from the background of social media will always suggest things like facebook likes which I did also when I was a newbie. But when they grow into the system, they will understand that this system although is not close to perfect but is not also bad. By then, they will stop trying to suggest many changes to the forum.
I don't think op deserve any insult because he does not understand how the forum works. We should always easily correct people especially when they do not understand how the system works. Some persons were advising op to give out merit as a means of saying thank you. How would someone that do not have merit nor understand how the merit system works to give merit? That should be so because the forum is seen like a regular social media when people come and enquire about something, if they get answer to there enquiry, thank you would be the compliment not sharing merit just like the person opinion I saw on this thread.
I must say that I appreciate this advice, many are in the forum who are not just considerate as you do not know the mental health of the person you are talking to. This is why I like to be calm in some situations so that I will not regret my actions eventually. Although the OP is kinda rude too, the way he propagated the message is just as if he was blackmailing the forum management. If I must ask, who can he blackmail? Just as I advised him in my first reply, I told him that if he made his threat good, it was only the fastest way to completely get banned from the forum.
For Christ's sake, this is not a normal social media platform or any other forum that will enable the "Thanks/Likes" button as he wanted. And since he is not the first or the last to register here, he must admit and obey the rules of the forum. Peradventure he can't obey it, there is nothing wrong in excusing himself from the forum if our deeds don't tally with his. That is civil enough.
