There is no statment in any of of the documentation thats states, that changing the value of nick-ien will solve this issue.
This will only tell eggdrop that your network uses 15 character nicknames.
Handles are somthing seperate (allthough, linked), which are limited to 9 characters by default.
You can fix this by doing the following.
Downloading eggdrop
edit the file "src/eggdrop.h"
edit line "#define HANDLEN 9" to 15
save
configure and compile eggdrop.
Note: Doing this will make 2 major changes to eggdrop function. You will no longer able to connect to a botnet, unless the bot connecting is also set to a HANDLEN of 15. A lot of eggdrop partyline output is based on the HANDLEN setting to format the output, thus this will changed too.
