You may not be as “clumsy” as you’re thinking. Because you’re a brand new member of this forum, your ability to DM someone may not yet be turned on. The ability to DM someone gets turned on through a little experience with the forum.
You might be able to purchase your field by going to that thread and @-ing Sammy, asking him to DM you for such a purchase. That might get the ball rolling for you.
Please bear in mind that Sammy is in the process of getting caught up from a bit of (celebratory) absence from the forum. Sammy deals with more of the business side of Sapien Med, so he has a lot on his plate to catch up. My point is I’m sure he’d appreciate your patience with any delay he might have in getting back to you.
