[ALUG] Horribly off-topc, sorry - uk telecoms groups/mailing lists/forums?

I know this is off topic but I think there may be people here in the know and I've come up blank everywhere else I've tried. Back in the day there was a thriving community on uk.telecom* newsgroups but unless I'm missing something that has all gone. Does anyone know where such people can be found these days? Public forums, mailing lists, etc? Admin: feel free to delete if you'd rather I didn't ask here, Mark
