Email is the fastest way to reach a person. We read everything and reply to anything that needs an answer.
Reporting a broken tool
Please include the name of the tool, your browser and version, and what happened instead of what you expected. If a file is involved, say what kind and roughly how large — do not email us the file itself.
Requesting a tool
If you need something that is not here, ask. Requests that describe a real recurring job are the most likely to get built, because they are the easiest to get right.
Data and privacy requests
If you gave us your email and want it removed, email us from that address with the word remove in the subject line and we will delete the record. See the privacy notice for what we hold and why.
Post
Prefer writing? Ask by email first and we will send a postal address.
