Hi Anika,
Thanks for your suggestions. That would definitely help us.
Actually, we are very people (only 3 regular contributors) doing all the upload and proofread works in Bengali Wikisource. We have a huge backlog of non-proofread pages (almost 500,000 and its increasing!) and we do need some more (actually many more) hands to proofread them. ;-) So, we are thinking of every possibilities to make the project familiar to Bengali language-speaking people.
As we expect almost everyone one as new contributor, we want them just to focus on the proofreading part, so that they dont have to bother about the numbers, and thus the tool requirement. They won't even know that there is a tool to track their contributions in the contest, so no-one will show-off.
Aubrey told me that there is a tool to track their contest results in Italian Wikisource, but its there somewhere. I hope that can also help us.
