I'm qith you on the ethicality of shutting this and redirecting - though maybe it would stir MB into action? But I'm stumped as to how else we can link the WWGHA site to a new WWGHAA forum, which to me is the crucial factor.
Well, may I suggest a course of action? I'll just pretend you said yes.
Start a project board with a discussion thread for each major problem you need to talk about.
1. Which hosting company and what is the domain name going to be?
2. How do we direct members to the new forum?
3. What would be the design of the new forum - such as the theme, colors, boards, purpose, and so on.
Start working on each problem for a few weeks and figure it out.
Look, this forum might go down today forever, or might not get renewed next time, so if that happens you'll only have yourselves to blame for not having a refuge set up the way you want it.
I'm willing to help but I'm not going to do all the work, I have already done it for my own needs and desires. It's you people who have to do it. I'll be watching to see if that happens.
