The mailing list for listmasters using Sympa

[Miles Fidelman <address@concealed>]

Thanks to those who answered.  As noted, I'm specifically interested in 
discussion (n-to-n) lists.

When it comes to my question about "what's practical," I'm thinking more 
in terms of communications dynamics, not so much how long it takes to 
distribute messages - things like how the traffic balloons when 5000 
people are all responding to each others' posts.  At what point does 
n-squared traffic growth swamp things (both people's inboxes and Sympa).

Any experiences would be most appreciated.

Thanks Again,

Miles
