A calculation looks wrong
Tell me which tool, what you entered, what came out, and what you expected. That makes it much faster to check.
A note doesn't match practice
If a formula explanation or a practical note conflicts with how things are actually done, let me know. Procedures differ between laboratories, so it helps to know the setting you have in mind.
A tool you need
If a calculator or feature you need is missing, say so. I cannot build everything, but knowing what is wanted is useful in itself.
Anything else
