I opened all the three and made some comparisons.
It looks like the
forum.barrowdowns.com (where you can't navigate or log in) has the same entries and posts as
www.barrowdowns.com. This
69.51.5.41 seems to be a thing of its own or separate entity which has started growing to it's own direction. So I'm afraid that anything posted here in the 69. -pages will eventually vanish - so every post made, every reputation given, every PM's sent etc. will go too, or should we say stay here in the 69. -pages - when the Downs are back again.
But will things posted here in the Barrowdowns.com remain after the logging-problem is solved we probably don't know. It at least seems that different smilies and icons are not usable in that version of the Downs either so maybe even things posted / done there will not last?
So I'd say one should actually make back up copies of one's posts to be sure if one thinks her/his contribution should last. I'm primarily thinking about the RPG's and possible more "serious" discussions where people have invested a lot of time and thought to their posts. Also I'd refrain from giving any reputation before the thing is settled (I never had time to rep my great fellow-players and enemies after the last WW-game but I will be at it when I'm sure they will stay).
But as things are I'd encourage people to use the Barrowdowns.com and not the 69. -pages as the latter seem to be different from the forum.barrowdowns.com.
