I was an Adver/ThisIs poster but I'd been a BBC606 Forum poster beforehand. I thought I signed up on the TEF much earlier (unless I had another account that I forgot about?) but I did used to be a Guest lurker/voyeur on here, reading the arguments/bollocks/etc. My current account on here is only since 2014/2015.
What DV says is pretty agreeable. Organically the age level has risen and it just shows that numbers joining the forum are almost stagnant. Shame, always good to have some fresh meat. There is the comfort of "better the devil you know" in many regular posters but it can become tiresome (I include myself in that). Be good to see some new "real" accounts but it likely won't happen
