First of all congratulation on your project.
Now let's go to the criticism (constructive criticism)
You should stop to think a bit.
The website is getting a little confusing. You should stop massive adding campaigns and start to develop the site.
It's hard to find a campaign. You should implement some filters, and improve the details on the main page.
Things to consider:
1) Type of campaign available
2) Who can participate?
3) Maybe some expected valuation per week
4) A ranking system (maybe from user votes, or current participant’s number)
Thank you for so detaile feedback
1) Type of campaign available - We will add pics with types of each Bounty Campign on the first page
2) Who can participate? - Due that requirments depend on type of Campaign, this task complicate
3) Maybe some expected valuation per week - Good idea we will think about this
4) A ranking system (maybe from user votes, or current participant’s number) - Yes ranking system will be implemented. Voting system will be soon
