While we are still waiting for clarification as to when the unified language pack will be added, I (and others) are of the opinion it should be added sooner rather than later. I think it is important that this be made clear to the powers that be that this is important to us.
I took a gander at the embassies ("game world" forums to use the new forum nomenclature) and counted a combined 36 threads that have been active since August across the 3 domains in the 1-7 forums. ( I ignored x3 because that is rather messy) Those are the only sections of the forum where they is any conflict of adding the new combined language pack. About 1/3 of those were active simply because someone was dumpster diving into old and otherwise dead threads. (This is a big issue with the x3 threads and hence why they were left out of my count)
I believe it is entirely reasonable that those threads and the few that might be created over the next 5 months can co-exist relatively peacefully on the single language pack. All other sections of the forum will have absolute no conflict. Either an official tag can be created (not sure on the ease of adding on the tech front) OR a simple [US] [UK] etc. added to a threads title (and enforced by the Mods)
The only reason I can see that can delay this is the technical implementation of the language pack and the work that the staff will need to do to move the threads. However I suspect working on these threads will be infinitely easier than it was in the merging of the forums last year.
We the people ask that the new EN language pack be added ASAP.
(P.S I would personally request we see more archiving of old threads. Are there any guidelines as to when that function is utilized?)
(P.P.S The HoF is another issue but that needs a lot of effort to organize and rebuild it any, though less so the UK. They have down a pretty good job with it.)
