Retro networking / WAN communities

[Grant Taylor via cctalk]

Hi,

Does anyone know of any communities / mailing lists / newsgroups / et 
al. for retro networking / WAN technologies?

I find myself interested in (at least) the following and would like to 
find others with similar (dis)interests to chat about things.

 - 10Base5 / 10Base2 / 10BaseT
 - ISDN
 - DSL / ADSL / SDSL / HDSL
 - T1 / E1
 - ATM
 - Frame Relay
 - ARCnet
 - PSTN / PBX / PABX
