Hey Dhoni_183*, welcome to CW and the forum.
You will soon come to realize that posters here generally like to talk about test cricket, and if you see a general statement being made about a player, it will usually be with regards to his test career. ODI and T20s are also discussed, but are generally specified as such.
This sometimes leads to opinions on players such as Dhoni being rather underwhelming because his record in tests (in all the roles of captain, wicket-keeper, and batsman) hasn't been as great as that in the ODIs.
But you should carry on, and if you happen to change your mind at all on this (if it so happens), you can always ask the moderators to change your username
