Hello @Ciska!! Knitrias send me in her name to express opinions on your project!! Certainly there have been many groups of this nature in different forms. Delegating only, trailing only, or one of the most common because of the profitability: delegating and trailing at 100%, the later in my view is the commonly known as "Circle Jerk", they only vote on themselves.

The nature of a project must set the goals and, as Xpilar says, the basic rules of the operation. I find your project very important to fill some of the opportunities that existed before to participate and invest in a project that make company to a previous decision to keep posting, it's always good to set a basic review of the materials the trail is voting to encourage quality.

I think your conditions to participate are accessible but I think the target of the project could be more for users that already have those 500 SP or more. In my view, leasing or buying is not a good idea for members to join the trail, if I'm leasing or buying Steem to Power Up, is because I want to curate by myself for better reward for authors (projects, communities) or for better curation rewards for me (investors). For some people with less than 500 SP it will be simply impossible to participate.

I've seen you are inviting small accounts to join and be active. Maybe you can track somehow those users and depending on their record give them big support to finally join the trail. One contest here and there or other giveaways in Steem Power could be helpful.

As for the Knitrias Project we are delegating to up to 10 Members with 200 sp to vote at least 50% of the voting capacity between Members, the other 50% is free to distribute. We are setting a limit in the time of permanence as Member or the amount of Steem you need to stake to be considered a Graduate Member, at this point there will be other forms to participate. We are setting a minimum of 60% Steem Power of the liquid rewards, this is difficult and will be but the main goal of the Members in the Project is to reach that minnow level, after that they will have more possibilities to swim!!

Thanks for inviting us to the discussion, @Ciska!!
Best vibes for projects and life!!
