spawning

Hey nerds, ancient account that I never did anything with. But I'm fancying having a go at modding UO, and a lot of the tutorial links have rotted. So I've got a bunch of questions. I'll keep to the basics for this thread though. 1. How do I create Trammel's spawns, and select what is spawned...

I'm sorry in advance if this is going to be a completely noobish question, I'm about to try something bigger than tweaking some lines of code here and there in RunUO/ServUO and I could use some advice in establishing a good starting point... For the sake of learning the in-depth ServUO server...
