As I understand it there was a pre-christmas event Quest where you should gather some presents of different colors and give them to Santa.

Is that quest gone now when the christmas event has taken place?

Maybe you can get more information if you try to start the game from a terminal window.

Start a terminal and write:

tmw


Then an error might print itself in the terminal.

The missing file, SDL_net.h, seems to be in a package called libsdl-net1.2-dev

(Found out by running:
dpkg -S SDL_net.h
libsdl-net1.2-dev: /usr/include/SDL/SDL_net.h)

So try to do a

sudo apt-get install libsdl-net1.2-dev

get the source of 0.7.0 , compile and install and voila 0.0.24 works

Another possibility is to download the guichan-deb-packages from the Hardy repositories

If it shows 1/1 it means that you have one item selected, right?
Pressing + sign should only be possible if you have 1/2, 1/5, 1/40 or whatever.
When 1/1 is chosen pressing Ok or Sell or whatever name it is should be possible?

I think that Daggers only "stack" one and one so if you have 2 daggers you cannot sell them in the same transaction.

Ahh, filtering seems nice aswell. I was thinking of muting certain people of own choice. I don't want to hear what <PersonA> says (spamming, bad language or whatever reason) so I somehow select <PersonA> and choose <Mute>. His comments won't show up in my chat window. Would be nice.

It would be nice if it was possible to censor people.
