Trying to add "Responsible Mining" as a topic, but there's an error message that it already exists, which it does as a Metric name (https://wikirate.org/Edidiong_Uwemakpan+Responsible_Mining). This is clearly a gap in my understanding rather than a bug, but I had previously understood that cards of the same name could exist if they were different card types. Is that just fundamentally wrong?
There can only be one card with a given name on Wikirate (or any Decko deck).
A major benefit of this rule is that it means simple urls and links are possible. Eg, if there were two cards named responsible mining, then we couldn't have simple urls like wikirate.org/Responsible_Mining or simple links like [[Responsible Mining]], because we wouldn't know which one you meant.
In this case, however, you can just change the type of the existing card from "Metric Title" to "Topic". This won't change the type of the Metric card itself (you do NOT want to change the type of _that_ card!)
