At the risk of being off-topic .. regarding join dates ...
Way back (Cattleya and I time) it was based on trading forum time. However as people left and came back and left and came back, tracking that was a nightmare. I can recall sitting with bits of paper with <x member> posted here, seemed to leave here, came back here, left here .. .trying to add it up. We'd discussed the problems but not really moved on with doing anything about it by the time Catt decided to step down.
When sirpoopsalot and I updated the trade rules, we decided that we'd swap to forum join date. Whilst not perfect, it was easy to track and as we kept banging on about traders doing their own background checks to be comfortable, it seemed reasonable for members to at least do a search on how much a member had posted in the trade forum.
In retrospect, it was a good move because with the various forum migrations, tracking a members activity, isn't necessarily that easy.
And that's the background to the changes. Nothing is perfect and the forum is MUCH quieter now.
And ... back to your scheduled programming.
I am considering joining but something usually goes pear-shaped and I don't want to incite it. I'm thinking; you can probably hear the creaking.
