Hunter,

As fliburt says, you can turn off the signatures in your user CP area - there's an option for it. Quite why we have not implemented signature limits before now in vBulletin escapes me, but I'm sure that there's a good reason (just can't think of it right now!).

The IM links are useful to allow people to contact each other easily - and they only appear in the user's profile, not all over the board.

If you do have any specific suggestions, please do let me know.

Thanks,
John
