Telehubs+-vs-+Direct+Transport

When and why you might choose using Telehubs over Direct Transport.
As the Second Life instructions (see below for link) clearly point out, you have to choose one of these methods over the other when directing the teleport (TP) process to a region as they are mutually exclusive. It is also important to understand how a telehub will appear and is used in Search after it has been set up. The same is true if you should need to choose to use parcel landing points as they are mutually exclusive of a telehub and direct transports.

Telehubs
When initially setting up a region for the first time, users that search for your region are generally TP'ed to the center of the region by default. And if they use the Map feature, they have the ability to directly TP to any point they choose within the region. But that might not be where you actually want them to appear. For example, you might set up a classroom or welcome center to receive your visitors. A telehub is the easiest way to get you started with directing the TPs to a certain point within your region. Along with that, each region only supports one telehub. So this makes it very convenient as they are easily set up and used by anyone needing to direct a TP to a particular place within your region. And when a telehub is activated, it will also be put into the search database for all to find when they search on your region. It's also recommended that you configure the spawn points for the telehub in case you have a bunch of students TPing in all nearly at the same time. The spawn points will manage the incoming crowd so that they aren't falling all over each other.

The alternative to using a telehub is to use parcel landing points should you need multiple directed TP locations. If your region is parceled out, and you want to create landing points to some or all of them for your visitors to pick and choose from, then you should choose to go with setting up landing points. And if you did initially set up a telehub, no problem, you'll just need to remove it so that you can start setting up the landing points. Landing points and telehubs cannot be used together as they will interfere with each other.

There is a quirk worth mentioning here that needs some explaining as you might think it isn't working right when you first start to use the telehub. Both your region and your telehub will appear in the seach results. So, you're not seeing double. Also, when someone clicks on the landmark and intiates the teleport, they will indeed be placed at the telehub location regardless of which landmark they use. However, their beacon will be set (the little red arrow and and the glowing red cylindrical marker) to the center of the region. This is not really a problem, just something to be aware of. Of course, clicking on the red arrow makes the beacon vanish after the TP has completed.
