Off the top of my head, the two fundimental modifications I made were to 
remove the message-database limitations and remove some new-user questions 
I didn't feel like asking callers... but the most interesting change was a 
few lines of code to add a hook to catch script kiddies. I had no choice; 
my network was getting totally slammed with rogue Telnet traffic but I did not
want to inconvenience BBS callers by having to call on a different port.

If a non-ANSI user calls here, I know that 99% of the time its a script-kid. 
So I added a CAPTCHA; meaning, type the phrase you see. If you answer wrong, 
your IP address is blacklisted in the NET2BBS "kill" file. A blacklisted 
system is trapped and disconnected before the BBS loads. I write a 
seperate process that resets the kill file once a week in the case of a 
false-positive.

That has significantly reduced the amount of rogue Telnet traffic here and 
because the BBS does not load on blacklisted connections, the daily stats and 
logs are much more accurate.
