I am not to terribly concerned as the devs have been on point so far, but when you send SLK to the WEAVER SLK ICO address how long does it take before it populates yours current contribution? 25 confirmations....
This is handled manually by Matthew Langdon, as are all the tx's on Weaver currently.
Automated scripts will be enabled after the ICO and this is only being done to ensure that funds are correctly allocated to the corresponding user that sent them.
If you see the transaction confirmed on the blockchain and it matches the address in Weaver, rest assured, they're there.
