[3] The Riveters initially adopted many of the practices and shared infrastructure with the Timbers Army,[2][4][5] including the creation and coordination of large and complex tifo displays[2][6][7] and performing football chants throughout the match.

[8] Both the Riveters and Timbers Army are considered part of the umbrella organization 107 Independent Supporters Trust (107IST), named after section 107 in Providence Park that both groups use.

[9][10] Membership to the Riveters is open and does not require registration or paying dues,[11] though joining the umbrella group 107ist with a donation is encouraged to fund tifo displays and organizational events.

[12] The Riveters have a strong focus on inclusion regardless of race, gender, or sexuality, with explicitly anti-racist,[13] anti-sexist, anti-homophobic,[14] anti-transphobic, and anti-fascist[15] stances demonstrated in its matchday displays and public communications.

[17] A study of the Riveters conducted by a University of Portland professor found that most of the group's members cited a desire to support women's sports and gender equity as important factors in their participation.

[32][38][39] Supporters formed an interest group soliciting commitments toward a fund to purchase a share of the club[40] and protested outside of the stadium, and the Riveters, Timbers Army, and 107IST organized boycotts of team merchandise and concessions.
