hi Rahim,
Your first email to this thread did come from your personal email id. However, I do think that you should have stated on the email that you are taking this initiative as a community member and not as an employee of CIS. This is a practice that is common and standard practise among WMF staff who are also community members and it is worth doing so here as well as long as we have paid staff. The default assumption for any of your emails to this list currently will be that this effort is undertaken by you as an employee of CIS-A2K. If you are taking this effort as a community member, you need to state this upfront.
I have asked this question on Meta and you are free to answer there but I'm writing the question here for the sake of completeness of this email thread. I have read all the links on the page and have contributed to WikiData myself. I am no expert and I fail to understand what this Label-a-thon seeks to achieve. To give you an example so that you can answer better, an edit-a-thon seeks to improve an article on Wikipedia accessed by the general public. In a similar vein, what does this Label-a-thon seek to achieve? Can you please explain the same in simple words?
Thank you,
warm regards,
Pradeep Mohandas
