so my pool is "World of Hypno"; I'm trying to add my posts, but I don't see any option to do so. I checked from help and that page claims that there is an add to pool button, but I can't find it.

It's a setting you need to enable. Click "More" on the right-hand side above (next to "Help").

Then, under the "Users" list click "Settings".

At the bottom of your settings should be a checkbox for "Advanced Settings". Check it and then click save, and the Add to Pool button should appear on posts.

Edit: Also for pools, it's best to use the typical naming convention we use so that it's easier to search for. If it's original characters only, the pool name should look like:

Original - World of Hypno (Myuk)

Hope that helps!

thank you!
