Recording Schemes use a variety of systems as their home websites. Many of them ably assisted by BRC.
One choice for several of us was the NHM supported Scratchpad system. Used by 8 of the 30 Dipterists Forum Recording Schemes for example but also by Coleopterists and Arachnologists and a wide range of others around the world.
This was an "enterprise scale" project - the kind of cash that BRC or NBNt could only dream of.
The project will be shut down in September, sites will no longer be editable, just frozen
Details of this closure may be found on the GBIF Forum at https://discourse.gbif.org/t/scratchpads-scratched/3932
The international response has been considerable and a group has been formed to determine the best ways forward in an attempt by Scratchpad site managers to seek means of continuing the editability of their sites.
Two of our active sites are https://micropezids.myspecies.info/ and https://agromyzidae.myspecies.info/

Any expressions of support would be most welcome
