there is a signature campaign for jr members, see the signature campaign that I use. the minimum requirements to join the signature campaign are mostly members or full members, but now there are many sig campaigns that accept jr members
only a few Campaigns accept Jr. members, generally members and full members who are always accepted.
Many new campaigns but the fee for the signature campaign is only in the form of tokens for the project and the allocation for jr. members must be very small. commensurate or disproportionate that's what you get. can be combined with other campaigns such as social media campaigns twitter, facebook, telegram etc.
Following a signature campaign will also provide an opportunity to rank up but with quality comments.
