The old site had been collecting spam, so as I've imported the pages to the new site I've tried to filter it out where possible. I'm waiting to enable editing on the new site until I can find a better way to stop spam from getting added in the first place. If you have suggestions, let me know!
I've also built a way to import from a Google spreadsheet, and hope this might be attractive to people looking to contribute to the site. I'm very grateful for all the contributions that have been made over the years, thank you. I'd like to hear feedback about how I can improve the site for you. I'm aware that some of the data is quite out of date and am looking forward to spending some time focusing on data quality now that the new site is live.
I'm also looking at releasing a public API as I have received quite a lot of emails about this. Thank you for the interest and I'll post again here shortly with the progress.
