Hi Leo,

I'm not sure I understand the first question. The setting for those usually is set to TRUE for "isGuest" if the user is the guest (anonymous) user and "isSignedIn" if this user is signed in. Since guests don't actually login, it would make sense that the isSignedIn is set to FALSE for isGuest users.

Regarding the second question, I'm not seeing the behavior you're describing.

I created a list and created a column called "study_time_t0_event" and it appears as the header label as "Study Time T0 Event", so it should just replace all underscores with spaces, regardless of whether there is a number or not.

When I did this testing, it was in Trunk. What version of LabKey did you notice this behavior on?

Regards,

Jon
