A "SeaMonkey-Zone" similar to <https://developer.mozilla.org/en-US/Firefox> should be created with artwork, table of contents and so on to grant some "corporate identity". Related to "Bug 1151461 Create a landing page on developer.mozilla.org for the start page in SeaMonkey MailNews", but not blocking that one.
You don't need a bug for everything. Just go do it.
We currently have a goodd solution for "Bug 1151461 Create a landing page on developer.mozilla.org for the start page in SeaMonkey MailNews". So no additional SeaMonkey related contents is required, and so currently there is no need to create an own WeaMonkey zone.
With https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines we now again should think about a SeaMonkey zone. I haven't a clue how to do that.
(In reply to Rainer Bielefeld from comment #3) > I haven't a clue how to do that. It is a wiki so I have created a new page (see Bug 1151461): https://developer.mozilla.org/en-US/docs/Mozilla/SeaMonkey Currently this is a stub. Any contributor can help add content. You could for example copy or adapt information from: https://developer.mozilla.org/en-US/Firefox https://developer.mozilla.org/en-US/docs/Mozilla/Thunderbird
