I've just realised I went and created a large number of multi-word tags that don't separate their words with dashes the way multi-word tags are supposed to. Examples include:
proofofstake, which should be proof-of-stake
proofofwork, which should be proof-of-work
performanceoptimisation, which should be performance-optimisation
contractdesign, which should be contract-design
denialofservice, which should be denial-of-service
Of course, I don't have enough reputation to correct the tags or create the appropriate tag synonyms. What should I do?
