The tag info for manipulation reads:
The technique of disassembling two or more parts from one another.
and all existing questions are actually about this.
However the word manipulation has a much broader scope than this, which is suboptimal for two reasons:
- It may lead to people misusing the tag.
- People who want to search questions about disassembling Lego cannot find them, as they cannot find the tag.
I therefore suggest to rename this tag to disassembly, dismantling, unbuilding, or deconstruction (and make the others synonyms).
