Need help on Intial Start up Process for Community Contribution

Hello Community Members,

We would like to contribute to the Pentaho community for which we require certain clarifications on below:

1. Do we need to create seperate accounts for Forums and JIRA (to start our contributions) or we can use one common account for use on both mediums?
2. How do we need to proceed to do corporate contribution? As in, Do we need to create a Corporate account which can be used for all corporate contributions?

Quick help on these queries is appreciated.

Thanks,
Hiral M.
