This will block until usermgt returns, which could take seconds to minutes

in the extreme. Therefore, it is designed to be called by Ajax, with a

nice "Please wait" message on the frontend.

This will signal that the user has accepted the terms of the license

agreement, and will result in the user's database status being set to

"enabled". (Note that it will be set to "pending" for the duration of the

handling).

As such, it takes a single POST field, "declaration", which
|
|
64 |
must have the value, "I accept the IVLE Terms of Service".
|
|
65 |
(Otherwise users could navigate to /userservice/createme without
|
|
66 |
"accepting" the terms - at least this way requires them to acknowledge
|
|
67 |
their acceptance). It must only be called through a POST request.
