Corrections
The most useful thing you can send. Name the page, say what is wrong, and where possible link to the source that contradicts it. Pricing and feature details go stale faster than anything else here, so those are especially welcome.
What this address cannot do
Please read before writing

Suggestions
If you looked for something about AI image upscalers and could not find it explained plainly anywhere, that is worth sending. It is generally how the next page gets chosen.
