Hi,
It's a great challenge to try acronymising every word on a particular topic - like the chemical elements and other topics covered in the acronym tours. If you feel like acronymising a list of words like that but can't think of a good topic to acronymise, or you can think of a topic but don't have the knowledge or inclination to tackle it yourself, how about using this forum. People can post ideas here about things to acronymise, and others might see the ideas and decide to try acronymising that topic.
If you can think of a few acronyms on a topic but not all of them, that's okay - other people might fill in the blanks. Also it doesn't matter if the same words are expanded twice. Here are some topics I thought of - if you think of any others, post them here and maybe it'll inspire someone to start acronymising.
US States
US presidents
Capital cities
Musical instruments
Items of clothing
Animals (or breeds of a particular species)
Plants (again, you could limit the list to a particular type of plant, like vegetables or trees)
