# FAQs

**1. How do I start contributing?**\
Begin by selecting one of the active Datanets from the list. Each Datanet is focused on a specific topic or dataset type. You can choose any that match the kind of files you want to upload.

**2. What type of files can I contribute?**\
Each Datanet accepts only one file type: Text, Image, or Audio. Mixed uploads are not allowed, and files that do not match the Datanet’s format are automatically rejected during upload.

**3. What happens after I upload my files?**\
Every contribution goes through a validation process. The system reviews each file to ensure it meets data quality, structure, and relevance requirements. After validation, you’ll see both accepted and rejected files in your dashboard.

**4. Can I re-upload or add more files later?**\
You cannot edit or replace existing uploads, but you can contribute new files if the Datanet is still open and your daily upload limit allows it. Every new upload is validated before being added.

**5. Can I contribute to multiple Datanets?**\
Yes. You can contribute to multiple active Datanets at the same time, as long as your uploads follow each Datanet’s format rules. Your daily upload limit applies across all Datanets combined.

**6. What determines my rank on the leaderboard?**\
Your rank is based on the acceptance rate of your contributed files. The more of your uploads that are successfully validated and accepted, the higher you will appear on the leaderboard.

**7. How does the leaderboard work?**\
The leaderboard ranks contributors based on their accepted file ratio and consistency. Contributors with more accepted uploads and regular participation appear higher. Rankings refresh automatically every hour.

**8. Are there limits on how much I can upload each day?**\
Yes. There are daily limits to ensure fair contribution across all users:

* Per User Limit: 10 MB total upload capacity per day across all Datanets
* Per Datanet Limit: 10 MB maximum per day for each Datanet
* File Upload Limit: Up to 20 files per user per day

Uploads beyond these limits are automatically restricted until the next day.

**9. What if my files are rejected?**\
Rejected files are not added to the Datanet and do not affect your rank. You can re-upload improved versions within your daily upload limit.

**10.  Will all contributed data be visible in the All Data section?**\
Only text type datanets display all the contributed data in the All Data. For audio and image type datanets, the All Data view is restricted and does not show every contribution.
