But if you think this massage is helpful why not merit.
Everything was good but
this last line ruined it all. You need not ask for a merit, if the message is actually helpful.
You shouldn't ask for merit, but even if a message is helpful it might not get merited currently. There currently isn't enough sources to distribute merits. theymos did suggest in the future there will be a few hundred sources though and that should more than cover all sections of the forum and more posts should then be merited.
