I noticed some players are adding the Main hit and the following ups in the subjet as TD:

Why are they doing that ?????

i could not find a good answer, can you ? and should we accept these posts as the right way of posting ,

or there are some rules?

from my standpoint they may do that if they like...but for the actual TOP hits only the main hit will be counted....they prob do it as it adds more appeal to their topic

There are no rules as such on the posting of CR's
there are guidelines on the the best way to post though...as it improves readability

It is heavily encouraged but by no means compulsary, though you may end up ticking someone of if your CR posting habit is annoying

The TD is usually just the main hit and the followups are not added...unless you really feel that your hit is not very big and to compensate you need to add them in...
