Ahh, a few things the Manual.html addressed.
1. `b-w-i` Splitting Block workshop is 1x3 in size, use for converting 1 stone boulder into 10 rock blocks.
2. Splitting block requires Stone Craft labor enabled, not Mason labor.
3. In order to gain coins [500], build Merchant Stalls out of 3 rock blocks.
4. Merchant Stall - select the merchant you can to Sell to.
Bringing battle axe can get fell trees in early game, so you can sell 10 rough logs for 500 coins.
Or you can sell 2 feather wood (Good Biome only) logs for 500 coins.
Evil Biome only logs sell for more, as well as some of the deep cavern fungus logs.
5. Questions: What labor is allowed to sell to Merchant Stalls? Is it just the Broker? Assigned Bureaucrat positions too? Or anyone?
If I sell threads and cloths to the Merchant Stall - Textile; does the person need Weaving skill enabled?
After obtaining stacks of coins, a little micro-management is needed.
6. `b-w-Ctrl+g` Build Guildhall (7x7) using blocks (wood planks don't work) plus 4 chairs/thrones (early carpenter shop using rough logs, or mason workshop using boulders).
7. `q` Select what type of Guildhall (Merchant's Guild) for coins (500 or 1000 not sure).
8. Assign a Manager in noble screen if you have not done so.
9. `q-P` Profile the Guildhall, and Assign One specific person yo want to join the Merchant's Guild for 500 coins.
10. `q` Guildhall, Join Guild for 500 coins, and the one assigned profile will go there and become a guild member.
Remove the guild member from the profile list, and assigned the next person you want to join the guild member.
Now here is where I messed up, or was just confused. And this was how I successfully upgraded the Guildhall.
11. `b-w-Ctrl+n` Build Guildhall Extension North (cost 3 blocks). I put this 3x7 north of the Guildhall, but I read that it can be placed elsewhere.
12. `q` on the Guildhall, select buy Extension North (costs 1000? coins), after this, will enable the North Extension.
13. `q` on the North Extension, select the available type of workshop this North Extension is (costs 500? coins).
Ok, so far, so good.
Question: How or where or what menu, do I buy "contracts"?
Manual says I can get it from caravans. I built a Trade Depot, and traded as normal. But there is no option to buy contracts.
I built the Guild Hall - Merchant's Guild (North and West), and it does not have the option to buy contracts either.
