It said that Satoshi lost the first forum which he was using a to post about bitcoin development. A SourceForge forum. That Sirius (could it be this Cyrus) provided hosting for the present day Bitcointalk we know.
Cyrus and
sirius are different person.
Thank you for proving me link to
sirius. I checked the profile and I discovered that he did not get much merits and trusts like Theymos and Satoshi. It was only Theymos that trusted him as "co-creator of bitcointalk"
Merit wasn't implemented yet on the time when he was still active even trust feedbacks wasnt fully used on that time compared to now for DT members.
Theymos trusting him as co admin is enough for all members here to trust him as well.
