If you receive a notification that someone wants your offer, it means that the Poster has asked if you can do their task. The notification will look like this:
If you think you're suitable for the task and you're interested in completing it, go ahead and make an offer on the task. Should you have any questions about the task, you can post your question in the comments section of the task page.
If you don’t want to make an offer on the task, we encourage you to let the Poster know. This helps to build rapport with the Poster and increases your chances of them considering you for future tasks.
