talking to other owners in the guild???

how do I go about talking to the other owners in a guild I just joined??....all the guild says is do I want to ask for heal kits???I don't even know what that is or does.
Use the chat; on the left of your screen is a white arrow on black. Click that. That is also where you will see people asking for heal kits. To ask for your own just click on your Guild Hall. Options will appear at the bottom of your screen, one is the red heal kit, click that.
