Several newbie questions

Hello,

I recently installed Licq, and have browsed through the various options, but 
some questions remain:

1) Is it possible to send messages with Enter and insert a newline with 
Ctrl-enter, which is the opposite of the default.
2) Is there a way to delete groups? I have no use for "Other 
Users", "Buddies", and "Top Level".
3) Is there a way to reset my contact list on the server, so that all contacts 
will always show by whatever alias they have selected, instead of things I 
may have set with other ICQ clients?

Thanks!
Georgi
