More generally, WebHints do not bring any data back into RM for any of the WebHints partners. All you get is a light bulb that is a link you can click on to to see the data at the partner site. If you like the data you see, you can bring the data back manually by typing it into RM.
WebHints are not stored in RM. Any data that is stored about a WebHint is stored at the partner site. For example, you cannot search in your RM database for individuals with WebHints, you cannot color code individuals in your RM database who have WebHints, and you cannot make a group in RM based in individuals who have WebHints. All you can do is to display a person in one of the RM views and wait a few seconds to see if a light bulb appears. If a light bulb appears, you can click on the light bulb. But there is no way to know in advance if a light bulb is going to appear or not. The RM views that support the light bulbs are Pedigree View, Family View, and Descendant View.
The only automated feature of WebHints is for the FamilySearch Family Tree site. For that site, RM has an option called Match person to FamilySearch when hints found. RM has a partially automated way to move data back and forth between your RM database and the FSFT community tree. RM facilitates the movement of data back and forth between RM and FSFT in the sense that you don't have to type it in again, but you still have to specify exactly which data is to be moved back and forth. Before data can be moved back and forth in this manner, an individual in your RM database must be matched to an individual in FSFT. Enabling the Match person to FamilySearch when hints found option will facilitate the matching process. There are other ways to do matching between RM and FSFT, but WebHints can sometimes make the matching process easier.
