Hi Ram,
Welcome on the project !
First step is to get familiar by reading the whole contributor guide
:
http://wiki.sigmah.org/doku.php?id=contributorguide:contributorguide
And if you are curious about the Sigmah project, you can follow it
on social networks like :
Twitter,
Facebook,
Linkedin,
Google+.
Regarding the issue #1058 you have chosen, it might be a little bit
tougher than what you may expect, but it might still be easy with
some work.
Issue #697 might be a little bit easier.
Tell me which one suits you the best. And as described in the
contributor guide, create your user account on our Mantis issue
tracker so that I can assign your prefered issue to you.
Have a nice day,
Olivier.
