Hello @monisikder dear - I like your choice of interesting subjects - it will help protecting you from criticism though if you simply acknowledge the source of your information.

You can do this by typing "Source:", then pasting a link to your source into your post in the same way that our friend the fearsome @cheetah did in the comment above.

It is a slow and at times painful learning curve, but perseverance in spite of the embarrassing moments will get you where you want to be in the end!

Huggs - looking forward to the next helpful hint you find to share with this community!
