I don’t remember the thread either. The two companies are Entrust and Mid Ohio. You can find them by going to the top of the page and you will see their banners to click on. You can also read some articles in the How To section of this site.
Can someone send me the message number of the recent thread on using self-directed IRAs for REI? A couple of companies were mentioned. I think it’s fallen off the board- or at least I can’t find it (too long at the computer today?)
