Thread:Project talk:About/Contact us section

When drafting the contact us section I noticed that on Translating:New project it mentions contact us "...by e-mail, Instant Messaging...". Is it possible to contact the project (not individual users) this way and, if so, how?

Also, does translatewiki.net have a physical address yet? Has translatewiki.net been registered in any country as an organisation yet? If and when that happens, the contact details can be added.
