Well, the backlog is back up to 20,000 transactions. Some will clear, and others will cancel. This backlog is like a clog, it is best if we clear the entire clog out. Some of the backlog transactions are connected to the old code, and most of it is based on the new code. We really need to clear out all of the transactions with the old code ASAP. Let me make this simple, please don’t do any TBC transactions this weekend at all. Offering Kringle Cash gifts is not a problem at all, since the coins are issued at the same time the wallet is created, so it’s not really like a regular transaction and doesn’t add to the backlog. So, give gifts as much as you wish by sharing your link to Kringle Cash. Outside of that, just don’t do any transactions at all this weekend, and we hope to clear this Clog/Backlog by Monday. It should be smooth once this backlog has completely cleared. We continue to add more servers to the coin network to increase capacity to complete transactions and have them confirm on both ends quickly!
