Should two-word tags be separated by dash?

Question

This question has tag currencyexchange, shouldn't be currency-exchange?

I've tried to rename it, but it failed to do that.

Answer 1

Yes, the convention is to hyphenate tags that use multiple words. I edited this tag to read currency-exchange.

Answer 2

Based on this the fullnode tag should become full-node

Answer 3

Yes; and the same applies to:

• fullnode
• coldstorage
• tailemission
