Look at the upper right hand side of  your phone you will see a space with quote them click on the quote you will have the opportunity of replying to the person when you want to reply to but remember to give a little space at the back of the user's comment before replying to them. Do not be in a hurry to respond to every comment rather I will advise you read the comments of members so you will learn from what they have to say while you listen and read more. The forum is very easy to navigate just give yourself time to stay online here and learn from lots of links that will be provided for you where you can study and become more knowledgeable than you are on arriving here.
