What if I don't know what's causing my problem?
That's completely normal — just describe what you're experiencing as best you can. Techs are used to diagnosing from vague symptoms.
Is there a minimum request size?
No — from a five-minute question to a multi-day project, all requests are welcome.
How fast will someone respond?
Response times vary by tech and urgency, but most requests get attention quickly, especially urgent ones.
