Do you think it's really necessary? The bounty campaigns are held right at this forum, which is a way for people to advertise their ICO. So, there are not any other websites that are used by everyone for the same purpose.
The slack page is good for those people who always visit slack for various things ahead but I don't really think its the most better idea to join with, since the furom itself offered those campaign and it has been placed on the right section so that people will not lost on other boards to seek those best campaigns for them.
