Hi @mhsiddiqui
Thanks for reaching out and welcome to TWB 
I’ve moved your post to this thread where you can find guidance on how to find and claim tasks!
Before you start working on a task, you must first claim it! This lets other translators know that you are working on the task 
Once you claim a task, you will be able to see the source text in the online translation tool, Memsource!
If you’d like to check out our Translator’s Toolkit, it has lots of useful resources to help you get started with TWB
