Hello akash , First a mild warning to stop you getting into trouble with the forum editors , you must not plug ( spam ) a product on here unless you are doing it to help somebody with a question that you know the answer to.
If you want to put a websites information in a post this is how to do it. The link below is for amazons home page , note to others , I am not advertising a product I am just giving an example of how a link works You go to a website then right click to copy the address , come back to your text box here and choose paste.
Note when YOU paste the site into your text box you will see the full address but others will only see it as a "click here" icon.
It is also possible to copy and paste any item from you pc that you might want others to read. See the example below.
Whenever I answer a question I type it into word and save it in case I want to use the same answer for somebody else and then I don’t have to keep retyping it.
