Hi Caitanya,
You can give people a link to your world's World Page. It they press the Enter World button when they aren't already in that world then they'll be teleported to the world's landing point (or to 128/128/128 if none is defined). HOP should also work with viewers that support that protcol.
The following is a quote from of our own internal wiki:
Overview
When a user enters a world, the position he appears in depends on several things:
Whether the world has multiple regions
How the user entered the world: login, teleport (there are several types), or crossing
Whether the parcel has a Landing Point set, and what is the Landing Type
Whether the region has a Telehub
Whether a starting location was defined for the world in Kitely
Starting Region
In multi-region worlds, the starting region can be determined in several ways:
Each world has a default region, which is the starting region if none of the cases below apply
Some types of teleport specify a location, including a region: teleport using map/lure/landmark
In a manual login the user can enter the region name in the viewer
Default Region
Each world has a default region, which is the starting region if nothing overrides it.
Users define the default region by setting a Telehub in it. This is just a convention that we have defined: when a Telehub is set, we set that region as the default region for the world. The user can then delete the Telehub, if he wishes. If he keeps the Telehub then it behaves as usual.
Telehub
A region can have a Telehub. Users who enter the region via login or teleport appear near the telehub. Note that the telehub works only if the estate setting "Allow Direct Teleport" is disabled.
The Telehub affects only the region it's in. The Second Life documentation says that if an estate has just one Telehub then it will affect the entire estate, but this hasn't been implemented in OpenSim. See
http://opensimulator.org/wiki/Chat_log_ ... 2012-01-24 for a discussion of this feature.
The telehub won't work if the world is in multi-region mode and the user enters one of the other regions directly (any region that doesn't contain the telehub). That's because we accept the user's desired region (we don't make him enter the default region), and once he's there the telehub doesn't affect him, since telehubs only take effect in their own region. We could fix this by forcing users to enter the default region, but we haven't done so yet.
Landing Point
A parcel can have a Landing Point. Users who enter the parcel via login or teleport appear at the landing point.
To set the Landing Point:
Place the avatar in the location that you want to set as the Landing Point
Right-click the ground and choose "About Land". (If the land isn't visible then you can also access this dialog in other ways. E.g., in the Second Life Viewer, select from the menu: World > Places Profile > About Land.)
Go to the "Options" tab
The Landing Point will be shown in this tab. Click "Set".
Change "Teleport Routing" to "Always" or "Landing Point".
The Landing Point is saved in the OAR.
