Hi,
I have a doubt on the comma usage.
When a subordinating clause precedes mail clause, a comma is necessary between the clauses. Similarly, is a clause needed when a phrase or a opening word precedes mail clause.
e.g.
Taking out his gun, Steve shot the bird that was flying high in the sky.
Having said that, I would also like to say that all that glitters is not gold.
Similarly, one should try and guard against fake recruiters ...
Regards
