Does anyone know how to contact Tim?

Hi all, we all know that Tim is usually very busy and it's hard to get in touch with him. For everyday work on the project, this is not a major problem. However, there are tasks for which Tim's hands are necessary. For example, uploading ISO images for Ubuntu 18.04 with TDE 14.0.5 into the official mirror system, adding Ubuntu 18.10 (Cosmic) to QuickBuild, creating GIT repositories for next applications, changes to web pages, etc. The problem is, there has been no way to contact Tim for the past 1.5 months. There is no reaction to mails - neither in mailing lists nor in direct contact. At Trinity IRC rooms Tim is not present. Every attempt to contact Tim over the Internet is unsuccessful. Please, is there anyone in the mailing list who can get in touch with Tim? Is there, for example, someone who has personal contact with Tim and can tell him that there are some tasks for which he is needed? Cheers -- Slávek
