I'll be updating this with downloads for my dwarf fortress mods whenever I make a new one or have one to the point where I feel okay about releasing it.
Feel free to use the comments to report bugs and issues
Here's my first mod I made, recently updated to make it work better: it changes giant cave spiders to be tameable (via having them not be adults from birth - they have 2 in-game years after birth in which they can be tamed,) usable as mounts, and able to be trained for war, among a couple other little tweaks to them.
