I am an individual and would like to register a ".sm" domain.
Nic.sm provides forms for individuals to send them by fax or mail and information for payment is also available. The cheapest reseller that I found wants 135 EUR per year, whereas the cost at nic.sm is only 50 EUR a year.
EDIT: The lengthy rules at nic.sm mention that they deal only with authorized resellers themselves. However, nic.sm links to Telecom Italia San Marino as an authorized reseller (at the top of the link list, in bold). Telecom Italia seems to follow the exact same procedures as nic.sm (the difference being that you send the forms to them instead of nic.sm).
So the question remains: does Telecom Italia San Marino deal with private individuals directly? I wrote them an email some days ago with no reply.
