You can't add them personally as you are restricted to entering club challenges even as a member.
There is also an issue that if you add your results from a single event then all your opponents suddenly see a single result for the whole event when they know they played three of four matches. That's confusing and usually results in them emailing us. It's particularly unfair if that single result wasn't a good one for them and it causes their level to go down - very annoying if that's your only bad match in the whole tournament yet that's the one on the system. This is what normally happens when one player, who had a great tournament, enters just their own results!
So the rule is they either all go in or none of them go in.
It's possible that the results can still go in even if they're not already there. It somewhat depends what system it was run on. If you can find out then please let us know and we may be able to connect with the system developer. Not really feasible if it was run on Excel or bits of paper though.
Having said that, if someone is prepared to hand enter all the results then we can support that and give then the appropriate admin level to do so.
