So what are the weapons and upgrade system you ask me? Well, the weapons system is an interesting thing! Upon signing up to this site you will be asked to pick a Weapon Specialization!
What is this? Well, a Weapon Specialization is a weapon of your choice that you wish to become a master of. You may only have one specialization per character, and changing requires permission of a mod or admin, and it also requires you to give up, without selling them, your old weapons and you must buy new ones of your new class, starting from the bottom rank.
Btw, here are the weapon classes available:
Sword and Shield
Crossbow
Twin Swords
Two Handed Sword
Spear
Axe
What does this mean? Say you have Goddess Crossbow, the strongest Crossbow out there, but you want to move to Sword and Shield, you must remove all of your current Crossbows from your Item Storage, Pouch and etc, and you CANNOT SELL THEM, and go buy the Basic Sword and Wooden Shield and start from scratch.
As you may have guessed, there is also a weapons upgrade and rank system. Each of the different rank are as follows:

Now! Everyone automatically starts off with the lowest rank of whatever weapon class you're in. And while you can only buy the most basic form of all weapons, meaning you can't buy your way up to the top rank. The way to get higher up in ranks of weapons? Simple! You upgrade your stuff by using treasures and such you find in dungeon runs or buy from Beedle. Then, with a little bit of time, and a little bit of rupees, bam! You've upgraded your items!
Keep in mind though, that the stronger the weapon, the more rare treasures you'll need and the more rupees you'll need. Now! Get out there and get going!
