The subscription thing can be set up differently. It can be automatic so every post you make is subscripted or you can do it more selectively. The forum default at the moment is automatic subscription through the control panel.
I've just realised how this new site makes it harder to distinguish between post and signature block. I thought this was about the National Institute for Health and Clinical Excellence and MSR was posting about Homeopathy!
If it were up to me I'd keep the medals but bin the post count and lose the senior member tag. Just gets rid of elitism as we're all members who aren't mods or admin.
