Hi @mitul3737,

We believe sufficient time has passed for a lazy consensus. We would like to replace @Mouly22 and @ikramulkayes with @Arindam200 and @sajibAdhi.

Maintainers will update CODEOWNERS file first (via #2134).

In the meantime, please leave comment here to confirm that each approver candidate (@Arindam200 and @sajibAdhi) understands the policy and information for localization approvers.

• Policy for localization approvers (to be confirmed by candidates) #723

[sajibAdhi]

Hello, @seokho-son
I understood policies and information for localization approvers.

[Arindam200]

Hello, @seokho-son!

I fully understand the policies and information for localization approvers.

Thank you.

Thanks! let me close this PR and continue settings in other PRs.

• Update cncf/glossary external_collaborators people#248
• Update CODEOWNERS #2134

By the way, I'd like to clarify that we don't say a localization approver is a maintainer of cloud native glossary. :)

When introducing oneself, it would be more accurate to mention a localization approver or involved in maintaining Bengali localization. (there is no role name called localization maintainer as well - so far).
