I have always just used the DPSP options in our 401k but now I want access to more mutual fund options and want to use the brokerage link.

What should I know about the brokerage link? Any additional fees? Does money go into the brokerage link automatically or so I do it manually every 2 weeks? Can I still do a 401a to Roth IRA? Can I have ALL my money in the brokerage link?

Any info you can provide on this would be great. Thanks!
