How to include links of other sites here on TFG

Though adding links of other sites here on TFG is not allowed, but to some extent if the giving of links becomes necessary then you can give the links.
But before giving any link of any other website, you must follow these rules:
1. Add another tag with your Href tag that is rel='nofollow'. For example IndiaStudyChannel
<a href=""rel='nofollow'>IndiaStudyChannel</a>

2. You can also give a clickable link by using target='_blank' tag.
For Example IndiaStudyChannel.
<a href=""target='_blank'>IndiaStudyChannel</a>
3. You can add the links of this site in your Articles directly using href tag.
