Give option to remove "mobile online" users

[V S Rawat]

messengers, especially yahoo showing those users online that are on 
mobile. but when u send message, it allows a few or only one message 
to go, and then they have to reply before you can write further.

It is no good really, people log off from pc, and set them online on 
mobile, thus they appear online all the time. I am fed up seeing some.

Give us option in some next version, so that we can Hindi those who 
are "mobile online". I wonder whether others are also finding this 
problem.

Thanks.
