2- How to disable multiple select template, what i need is, only default template only use all the time.
Edit the template. The select input is added in login_include.htm and is generated by the <%GMail::template%> code. Comment, or remove it. You might also want to include the html: <input type="hidden" name="t" value="template_name"> in its place too.
