Subscribe to 5 categories, earn 500 satoshi
Just click the star icon on 5 different topics and you will be subscribed to them and receive email alerts when new tasks appear under those categories.
Just let me know if you've done it, and I will verify and send payment.
You should be willing to stay subscribed for 1 month. I'll send you a positive review after a month if you're still subscribed to at least 5 categories. If not, I may give you a sad review.
