I know I'm personally of the opinion that the server should use the database to load the spells instead of from the spells_us.txt (and maybe one of these days, I'll figure out how to change it that way), so I've already done so. That way, I can incorporate the information into web pages, etc.
The only "issue" is that, for servers that use custom spells, you can't just use a standard import. That's why I created
this PHP script to do this for me. The only downside is that it doesn't currently take into account older spell files, etc, with fewer columns than what the database holds (easy fix, just need to get the changes committed).
Anyways, I think it would be a good way to go.
