Clients don't you just love 'em?
Me: Welcome, here's a helpful guide that would help if the client should run into issues.
Client: woolly! Problem, fix it now!
Me: Asking client clarifiny questions about said problem? And for good measure also includes in the message a way to fix said problem. (Since they clearly didn't read welcome message)
Client: ...
Me: Asks follow up questions and give more ideas to fix problem.
Client: ...
Me: ... drums fingers ...
Client: ....
<several moments later>
Client: woolly! More problem (unrelated to previous problem which is still not solved)
Me: *thinking* you clearly didn't read my messages above, didn't you. <Takes a deep breath> Asking again clarifiny questions and repeats above messages, since the fix in the welcoming message would have fixed both issues.
