Unable to respond to a private message

[Ener]

Another user of the forum have send me a private message, however when I choose the reply action no recipient is filled in in the message form, nor can I write his/her profile name manually.
The profile doesn't show up if I perform a search in member list either.

Is there anyway that I can respond to this persons request ?

It is possible the person deleted their id after messaging you. Especially since you can't find them in the member list. That seems like the most likely reason.

That would make it difficult to get back to them, oh well.
Thank you the response.
