From what you say, I think I misunderstood how local merit sources work. I thought they were limited to give a certain amount of merits in that specific local board. Isnt that the case? If it isnt, I think I made mistake when I applied to be a merit source, I should have applied to be a local merit source. I didnt because I spent much more time on the English section than on the Spanish one, although I visit the Spanish one regularly.
You can award merits in every section.
If you couldn't you could use your Source Merits in one section that you applied for and your Spendable Merits in another section anyway so I think Source Merits are a global thing...
