I love it when it happens to me, but +100 for a n00b like me is counter-productive. I'd say at most +50, and phase out when you have >5 accounts (maybe that's already the case?).
100 rep isn't that much and gives you enough to:
To me these seem like things that don't cause much damage and someone who is relatively trustworthy and knows the system (from their other account with 200+) should be able to do. I think it would also be frustrating and off-putting for someone who already knows the system to not be able to do these things. They're also less likely to be a sockpuppet.
On the other hand, someone new to the system needs to understand how it works before being able to do these thing and won't be as frustrated by not being able to as they (unless their rep is between 100 and 200) never could.
