merproject.org is registered by David Greaves (and I would add, who else could have been ).
You should have plenty of ways to find his contacts, including whois data.
And I would suggest to first contact Mer people in their irc chat to discuss about the forum subject and perhaps also open a Mer 'bug' (as feature request) that you can assign to yourself about the forum creation, so things are nicely tracked from *inside* Mer project.
