For newbie's like me I don't think if they are another information sites that could helps bounty participants to track bounty campaigns movements. Telegram and Discord are one of the applications that I would like to use it is more easy to use and it is convenient even in mobile phone you can use to updates for all new bounty campaigns rules and guidelines. However I don't know if aside from that there are some apps or site that we can use to track your bounty campaigns pinned message, rules and updates.
