The Pololu forum was down or functioning poorly over the past two days. The issue should not have resulted in any lost posts, and everything should be up and running perfectly now. Please let us know if you notice any further problems.
According to our ISP, the new forum server started having problems with a RAID card just two weeks after we moved to it. They managed to bring the server back up temporarily without understanding the underlying issue, but eventually had to take it down again, replace the card, and run a lengthy check on the filesystem to get things working. We hope this means that our new server now has new, tested hardware in it, and we won't have any further bad luck!
Thanks for your patience,
