When I connect to a TF server i get this message: info string lenght exceeded bla bla bla and get kicked because I've wrong skin or whatnot. This won't happen in Fuh. I've to manually remove things from setinfo, and it's fuckin irritating since I usually get kicked anyway.

Any help?

There are no solution for this - userinfo is limited by quakeworld protocol and can be extended.

Write your config in proper way :E. Use as less setinfo space as you can.

i have a lot of experience here since i'm a tf player.

post your config and i'll help you

its a pretty easy fix just, load up your TF config before logging onto a server.
set cfg_save_userinfo "1"
then resave your config
and then re-load it.

see http://ezquake.sourceforge.net/docs/?config

cfg_save_userinfo
* 'cfg_save_userinfo 2' makes cfg_save save all userinfo variables like name/team/teamcolor/rate/msg/skin/w_switch/b_switch/... .
* 'cfg_save_userinfo 1' makes cfg_save save all userinfo variables except spectator/name/topcolor/bottomcolor/skin/team .
* 'cfg_save_userinfo 0' makes cfg_save not save userinfo variables.

Note : 'cfg_save_userinfo 1' is best for teamfortress so you dont get kicked for changing bottom color.
Note : cfg_save will never save the password variable, even though technically it is a userinfo variable.

I dont use ezQ's config manager for my TF config - it is hand-written from scratch
And i load my config with a command-line (-bla -blabla +exec tf.cfg)
