Suggestions and help on translating

[GamerArg13]

So, I PM'ed yvt to suggest him these things, and I am also posting them here to see what you think. Also I am trying to translate OpenSpades to Spanish, but I have a few doubts.

Suggestions:
*Ping counter, both in the menus and in-game. In a FPS, I think that a ping counter would suit perfectly, specially as I am from Argentina, and the closest server I have is in Brazil, with 150-200 ms approx; and it's quite annoying to use "/ping" every time.
(Maybe also a Kill-Deaths counter in-game, or a KillDeath-Ratio, I saw it being suggested in the forums)
*Display equipment being carried when using the mouse wheel (or number keys) to change weapons. I dont know how to explain it, but it appeared in the classic Ace of Spades. When you changed weapons or you used the mouse wheel; icons for the block, shovel, gun and grenade appeared on-screen so you could tell what you have, and where it was (number 1,2,3, etc.)
*Being able to return Intel to your base? I dont know if someone has already considered it, or how it would impact on the gameplay; but sometimes it is useful when your Intel is closer to the enemy base than yours, as the enemy carrier has been killed. It could have a counter to return, the defending team would have to pick it and return, or just pass by to be automatically returned; I dont know, maybe just consider it.
*Favorite servers. I think that it would pretty useful to have your favorite servers listed in one place, so you dont have to search for them constantly. (Maybe also a history or recent servers feature, that is also possible)
*Installer and game updater? Also, I dont know how difficult it is to make both things, but they may be time-saving for the player; also that with the installer you can remove the whole game with one click.
*Change--Language option in the startup window. This is something I cant understand, I know there are translations to russian, german and even korean for the game; but I dont know where you are supposed to choose the language. Maybe this option will make things easier for newer players.
*Aaaand I think there are a few more suggestions, but I dont remember them.

Translation to Spanish:
I have searched trough the game files and found the user-made translations... but I dont know where to start from, or which should I use as a template, because each one is different! (some are older than other, I guess, and their format change)
Now I am using the German translation as template, but there are some things that don't appear in the game.
Also I was wondering if I can include specific Spanish-symbols, like ñ, á, é, í, etc. If so, is there anything special that I have to do to make it work? Sorry for having so many questions, but I have never done something like this.


So, I guess that is all. By the way, sorry for any grammar mistake.
