Huggle should add Template:Shared IP advice after adding a new warning-template. If one alredy exists, then it should move it to the bottom of the page. This is not done on Huggle 3 build 860.

Version: 3.0.0
Severity: normal
As I mentioned in the comment above is is the {{Shared IP advice}}-template.
Here is an talk page which has the template: https://en.wikipedia.org/wiki/User_talk:216.228.169.149
Showing in the source as:
:''If this is a [[Network address translation|shared IP address]], and you did not make the edits, consider [[Wikipedia:Why create an account?|creating an account]] for yourself so you can avoid further irrelevant notices.''<!-- Template:Shared IP advice -->
This should always be located at the bottom of the talk page. If there already is one in another header/no-one exist on the page, then a new one should be placed as {{subst:Shared IP advice}} on the bottom of the talk page/current month.
Here is one talk page wich do not have the template:
https://en.wikipedia.org/wiki/User_talk:91.140.175.245
and another which has the template but not on the bottom of the talk page:
https://en.wikipedia.org/wiki/User_talk:202.153.83.3
If I remember correcly, I think that HG 2 did this (not sure!).
Ok, but I never see these on bottom of talk page. Since they are substituted, it's almost impossible to keep them on bottom. Other tools don't respect this as well. So I will do what they do:
If there is no such a template, append it to bottom of new message and keep it as that.
