Correct?

"request handler" sounds a bit inhuman to me. It sounds like part of a computer system.

Thank you for replying... hmmmm, then is there any way to put it differently?

seeker08is there any way to put it differently?

I guess it depends on exactly what the person is doing. What sort of environment is it, and what type of requests are they dealing with?

The person is dealing with lessons' requests... she provides people with recorded lessons on certain topics... people ask for the lesson they want and she sends it to them.

If this person is packaging up stuff and sending it out by post then "dispatcher" might fit as a job description. However, in customer-facing material "dispatcher" could sound a bit uninviting, and it's probably better to refer to an "orders department" or something like that. I think it depends on the exact context in which you are using the term.

Thank you for replying again. The person is doing that online. she's part of a study group, and she provides other students with the recordings of the lessons they ask for online... what can she be called?

Dear Mr. Seeker08,
In my perception, It is appropriate to address her as "Language Support Specialist" or " Support Specialist".

Why "language"? Thank you for replying... can she " introduce" herself as a support specialist?

Hi,
Anything which is taught online will come under "Support Services". You can simply say Support Specialist.

Alright... Thank you.
