When someone gives well reply and gets impressed with their effort but you are out of merits or zero merits in account. What is the better solution in this situation? I've noted few replies from member on my old post that they must deserves to get merited.
If you are in a situation like this, then just increase your post quality. If you make quality posts, you will receive merit so that you will be able to give out the smerit which you receive. I don’t think there is anything you can do if you have no merit. Or you can just submit a link to the post on the thread that @LoyceV created, if the post is really worth meriting, then people will definitely merit the post.
But you might even submit some posts that are useful to you, and they won’t be merited, because some posts might be useful to you, but other people won’t really find them useful, so don’t be disappointed if you submit a link and no one merits the post.
