I can see the helpful flags link in my SO profile. But I can't find it in meta profile.
Is this normal? where can I find it?
The link should appear as soon as you have at least one flag marked as helpful. It does not appear if you only have declined and/or pending flags.
You can visit the link manually (this link is specific to you) if you're curious about pending flags, etc. You can figure out your flag summary link by editing the URL to insert your user ID:
