You have the option to Solo mine on the pool instead of PPLNS mining.
Solo mining means that if you find a block, you get all the block reward minus the pool 0.5% fee. It also means that if anyone else on the pool finds a block, you won't get any reward from that block.
Normally, this would be of use only for large miners who don't wish to share mining with others, but are large enough such that the variance of Solo mining isn't high.
It can also be used by large miners who want to have their own pool, but wish to avoid the large overhead of having to setup and run a pool as reliable as KanoPool, and avoid the high risk of having to find others to manage the pool.
Solo mining for a small miner is high risk and likely to incur a loss due to the low probability of finding a Solo block. N.B. the expected return on renting miners is lower than the cost of renting them. See the Help->Luck page here for more information about mining.
To create a Solo account, you register on the pool and switch the account to Solo using the Account->Solo page. You will only be able to see the Account->Solo page if your are logged in to a new account or you have already successfully switched the account to Solo.
There are some restrictions on switching your account:
The account must have been created in the last 2 hours. You must not have pointed ANY miners at the account. You must have verified the account email under Account->Verify. You must have set a payout address under Account->Settings.
You will not be able to change the account from Solo back to PPLNS.
