"Guild" is misleading

I play ranked games with friend and we try to invite random people to join us, many of them have problems with using "guild system".

1. "Guild" in my opinion suggest something permament. I think it should be renamed to "party".

2. After each game you have to rewrite password/tag. I think game should keep your last used string. It would help avoid situation where player forgets what was the password or mistypes it.

3. It would be nice to add button "join party" next to password. If person didn't type guild tag it would be disabled.
