Migrated to Oracolo for now, since this is for an event happening on Saturday.
JavaScript based redirects kept the old site URL, including most important links pointing to the right notes.
The site looks almost the same, what is interesting is that it is faster than npub even though there's no caching.
Did a small contribution to Oracolo code.
