BX Rules Questions - Web Spells and Werewolves

I got to say, I've been running a PBEM Greyhawk game but 1 day playing the game on the tabletop really has me charged up! I think I might run my PBEM game to a close or hand DM duties over to one of my players. I want to focus more on getting a regular tabletop group together...

Well, back to the reason for the this post.


Question1:

The web spell B18: range 10', duration of 48 turns, covers 10'x10'x10', and describes how you can break out of the web using fire, giant strength, etc... However, it doesn't explain what would happen if a spell caster decides to try and cast the spell directly on a group of enemies fighting the party. Do the opponents get a saving throw to get out of the effect of the spell?

House Ruling: I gave anybody in the area of the spell a saving throw vs. spells, modified by DX, to jump/run/slash their way out of the web area before it fully "sets". What would you do as a DM? did I get it wrong?

Question2:

Werewolves - what are the rules on shapeshifting, how does the moon affect shapeshifting, what does the animal form look like?

House Ruling: I ruled that werewolves can shapeshift whenever they want between man and animal form, the animal form looks like a very large wolf with elongated arms that look more like claws/fingers than forepaws. I ruled that shapeshifting took 1 round to complete going in either direction. Also, during the night of a full moon werewolves shift into animal form for the entire night and will run rampant killing everything in sight and feasting on the flesh of their victims. Did I get this wrong? How would you change this for your campaign?

Question3:

Can charm person and hold person affect a werewolf? In both of their descriptions they say that they affect bugbears, lizard men, etc.. which are pretty different than humans... Also, a werewolf is pretty much a human inflicted by a disease.

House Ruling: I decided that given the description that I had for werewolves (they can think in beast form, but the curse affects their alignment turning them chaotic and evil - basically into beasts in either form).... I would allow these spells to affect werewolves in either beast or man form. I could see good reasoning to only allow the spells to work against them in man form, but I gave the advantage to my players at least this time... What do you think?
