Trying to figure out rigging in blender, I've watched a few tutorials, but am better off learning 1 on 1 where I can asked questions as I go along. help? If there are any Second Life players in here that would be even better.
You aren't trying hard enough with tutorials, find more tutorials until you find a good one that teaches you enough to fill in the gaps in the others.
You need a certain level of core competency before you can meaningfully interact with another person (unless they're literally a Teacher and thus willing and able to start at square 0).
I suggest you literally go fuck yourself, because learning to do that will be more valuable in the long run than using Avastar.
Blender includes literally everythig you need for Second Life, including transfer weights. Just make sure that your figure is oriented Z-up (it is by default in Blender) and is facing forward on the X axis. That is literally all you have to do.
