Stern Serial Number Masks updated
Serial number masks for Stern's Avengers, Led Zeppelin and RUSH Pro, Premium and LE have been updated to include the suffix letter "C". Many serialbot "5" scores are now 8s. I hope to update other serial number masks in the near future.

Couple Bugs Fixed
I got a chance to fix two bugs that John K. found earlier this month.... First one was that when searching serial numbers, the results were excluding GamePart serials. I fixed this and also added direct links on each serial number to the submission detail page. The second bug was that when submitting GamePart serial numbers, the site was not allowing a user to submit two GamePart serials even if the GameParts were different on that game. 

Both of these should be fixed now.. thanks again John!

IPSND is now a 501(c)3 Non-profit!
Hey everyone...  It took about 6 months of paperwork and fees but the IPSND (part of the ISND - Internet Serial Numbers Database) is now officially classified as a US Non-Profit. There were a couple of reasons that I took this direction...
  1. Hosting costs are greatly reduced for Non-Profits
  2. Donations are US Tax Deductible (not sure how that might work in other countries?)
  3. This keeps the IPSND money separate from my own money
  4. Ideally this makes things easier to transition to a new owner in the next 20 years.
More to come on this topic as the year goes on. Thanks to all that have supported the site in the last 16 years!

New Database Server too
Just brought a new SQL Database Server online tonight... had about a 30 minute downtime, apologies! Should be solid now and I will be mucking around a little more but I will try not to break anything.

New Web Server
Got a little upgrade today to a new web server with twice as much memory and twice as many CPUs. Hope that the site runs a little zippier now. I will be monitoring the performance and will see if I need to do anything to continue to tweak the VM. Next step will be migrating the database which will most likely happen the weekend of March 26th.
