JAYJUANGEE is a very good member on this forum, he as been active since he joined, since I have known him, he never joined a campaign but very active and distribute merit appropriately. I can say he is a very Iconic member on this forum because if his quality activeness.

I know FRANKY1 and DANNYHAMILTON too, both of them are good posters too and post more development and technical discussion, they are also good. FRANKY1 discuss better also in bitcoin discussion and what are related more to bitcoin.

But maybe you will still discussed further about this iconic members because they are still more, but if to talk of the ones that do not join signature campaign, I have known  philipma1957 to also be among them but many people may not know him as he post more in mining, many people do not visit mining boards often, but he post often, be got almost 39000 quality posts on this forum.

People like El duderino_ are also iconic too.

I think you only want to all about people that do not join signature campaign, but there are some other members which j will not mention yet because they join signature campaign but high contributing to this forum.
