Before you write

How fast do you reply?
You'll get a confirmation straight away so you know it landed. A person replies within one working day (Monday to Friday, UK time).
Do I need to pick a category?
No. Write what you need in your own words. Questions before you buy, a problem in the product or a security report all come to the same inbox, and we sort them from there.
What's worth including?
What you are trying to do, what you have already tried, and, if something is broken, roughly when it happened. It saves a round trip.
