1.Where can I find user ID?

User ID is something like "L94745762" or "845638450", you can find it at
A.Welcome screen: Figure 1.1 shows the welcome screen of DataKeeper.

(Figure 1.1, Welcome screen)

B.About screen: shown as Figure 1.2. To open About screen, you need select "About" menu from "Options" menu bar.

(Figure 1.2, About screen and Options menu)

C.Register screen: shown as Figure 1.3.

2. How can I register my software?

Registration code is something like L3847174932 - 847436528. Once you receive the registration code, you can use the code to register your software. At Register screen (Figure 2.1), input your registration code and then tap OK button. If the registration code contains letter L, you must input it as a big L.

• To open the Register screen, you can Tap on Register button at Welcome screen (Figure 2.2)

• Tap on Register button at About screen (Figure 2.3)

3. Am I correct that once you create a data type you also have to create a category to match each data type?  Data types and categories are actually the same thing; you just have to create categories to get your data types to show up on the pull down menu at top-right of the screen.

Yes, data type and categories are quite the same in some sense.  The software will automatically search if a category with the same name as the data type exists, if such category exists, the record will be set to be that category.   Data type is one way you can manage your data, you can set up the default field labels for the data type.   Category is the other way you can manage your data.  Suppose you have data types like computer account, bank account, website account, you may create a category called "Account" and you can set all of records from computer account, bank account etc. into Account category.  In addition, PalmOS only limits category to maximum 15.  That's why I create data type and let users use both category and data type to manage their records.

4. Is there a way to get the field types to "stick" to a category/data type so that when you create a new record you don't have to recreate the fields for each and every record?  Granted, it only requires a choice from a popup list, but it seems tedious.

Yes.  For a given data type, you need set default field labels for it.  Otherwise when you create a new record, all field will show as "Other".  To set up default field labels for a data type, go to menu "Options", select "Change field label" menu item.  In the screen showed up, select the data type from the popup list, and then select field label for each field.

5. Am I correct - there is no screen matching the one in DataKeeper with the check boxes to indicate which type of new record you are creating? You choose from the pulldown at the upper right?

Not exactly.  When you want to create a new record, you tap on the "New" button, it leads you to a screen called "Choose data type", there is only one check box there, all of you data type you created will show up in the popup list.  This screen is similar to the screen you mentioned in DataKeeper.  Since DataKeeper32 has no built-in data types, and I do not know what and how many data types you will create in advance, so I use one check box to include all data types you created.
