Sorry, can't agree. If them do 7plus job manually, its de-facto simpler
to make/collect/parse/process less big sized parts, than tens of small.
As for the occurrence of an error in parts, this has nothing to do with
their size, error can happens anyway and message will forwarded though
network first, then only processed for possible errors.
Also as we have mesh-type BBS network, according by its own essence,
it is likely that if there are more parts, then there is a greater
likelihood of losing some of them!
And counting that not all 7plus bulls senders may have proper configured
recovery utility (to re-send requested missed parts),
its also better send less number of parts!

I'm too know those OMs but some of them who finnally updated to s/w tnc
was totally happy and say just "why i'm not done it before?" :)

Its not a point, see two paragraphs above.
The only true point for small parts was from time where we not have so much AX/UDP/Telnet.
Most job was done on 300bd HF channels and/or on VHF 1k2 long range links,
say via 2-4 net/rom digis in line.
So the smaller parts was less stop mail flow and give chance to fwd some other mails
between 7plus chunks.
For today its have almost no practical sense, as most links are AX/UDP/Telnet
and most software also have possibility to put in first order private msgs and small bulls.

30kb - not a problem for 1k2.
Some ugly 20 years old KISS TNCs or poor s/w AX.25 stack maybe a problem,
but its the problem of its system operator, not a problem of 1k2 speed itself :-)
73, Sergej.
P.S. to all: please not change bull area - its harder to track discussion.
So, if topic stater send Q to ALL@WW, please reply to ALL@WW also.
