## Happy New Year

Wish you all a very happy new year. May God bless you and all your dreams come true. Also may our maths community enrich with ideas worth millihelens of beauty.

## how to add attachment

I want to attach a diagram alongwith my post. Can anybody please tell me how to do that, if not how could I depict my diagram whichis atmost needed

## Re: how to add attachment

I am also interested in the method for making attachments- not necesarily graphics.

## Re: how to add attachment

Is there any provisioning on planetmath forum by which i can attach something alongwith my post?
