Database upgrade complete

The database has now been migrated to new and upgraded infrastructure offering increased performance and resilience. is once again available for creating balanced groups for social, teaching, business and other events. Balancing groups on one characteristic (age, gender, skill level etc.) is easy, but for balancing across several attributes, you need Groupsort – the best resource of its kind on the web!

Scheduled maintenance

The site will be undergoing scheduled maintenance at 12:00 UTC on Wednesday 5th April (1:00pm UK time), whilst the databases are being upgraded. Groupsort will be unavailable for up to one hour while the work is being carried out, so if you are using the site on that day, please be sure to exit in good time, to avoid losing any work.
