Just preferences, but I would like to be able to see someone's signature in his/her profile. I disabled sigs for forums, and I do think it was an awesome decision, but I do feel like seeing someone's sig at times. So in that case I would love not having to enable sig, load all sigs in a particular page when I'm only looking for a specific one.
I don't think this is a particularly difficult thing to do, and it has no downsides to it at all. So I request for this change to be made.
While I have signatures enabled myself, this is definitely a good idea, and should be easy enough to implement, seeing how this was actually the case in the past on Fakku.
Dohoho, this is a really good idea, especially for those people who have loads of stuff in their sigs or their sigs are incredibly huge... I support this.
