I have an online service where users can ask questions to a particular kind of expert. User can then pay to unlock the answer and read it.
Normally questions are answered by first-come-first-served expert. Some users ask for specific experts to answer and I make a case-by-case exception. However experts may not always be active so I need to warn users that getting an answer can take a while.
Also the support burden of questions to specific experts is a lot higher and I want to encourage users to either opt for "open questions" or try other sites that allow this option.
So, this is how I have worded it.
> <service> is a self-serve platform that is designed to work with open questions. Questions to specific <experts> can take longer (days or weeks). We are unable to provide much support to help users with such questions.
> We encourage users who want to pick <experts> to try out other sites <link to alternate> which allow this choice.
Today I got an angry email from a user calling this "arrogant". How would you have worded this ?
