Sorry,
Present you can change threshold .
Perl,
The user interface is buggy though. I tried to change "Personal Threshold" from the default 5.0 XMR to 0.5 XMR but it keeps reverting back to 5.0 XMR each time I refresh or hit "Lookup" again. My pending balance is now way over 0.5 XMR and it's still not paying out.
Also, why is there a "Payout minimal interval" with "24 hours" as default setting. Is this necessary? Shouldn't the pool pay out once the "Personal Threshold" is reached anyway? Why the time constraint? It's very confusing and this option also keeps reverting back to "24 hours".
Both option features are broken and useless.
